DR 13-0014 — PML: omissions and inconsistencies in the specification of attributes - review of proposed resolution

[Francis Cave]

Hi all

I have reviewed Chris Rae's proposed resolution to DR 13-00014, based 
upon his analysis of the behaviour of known implementations, which at 
the London meeting in June 2015 we agreed was satisfactory, and on that 
basis we agreed to close the DR. However, the DR was never closed in the 
log, and as a result Murata-san added comments to the DR. I have 
therefore also reviewed all Murata-san's comments.

Below are the results of my review for each subclause listed in the 
original DR. In summary, we need further action on §19.5.4 animMotion 
(@ptsTypes) and §19.5.28 cmd (@cmd, @type), which is what we 
provisionally agreed in the meeting on 2017-06-19. All other items in 
the DR are satisfactorily resolved by what Chris Rae proposed, in my 
opinion.

Kind regards,

Francis


§19.2.1.17 kinsoku (@lang) (complex type: CT_Kinsoku)

Chris Rae's proposed resolution is to correct the schema to reflect that 
@lang is required in all known implementations. We agreed in the WG 4 
face-to-face meeting on 2017-06-19 that the prose should not 
unnecessarily duplicate information in the schema, so no further action 
is required.

§19.2.1.39 sldSz (@type) (complex type: CT_SlideSize)

Chris Rae's proposed resolution is to add prose to indicate how omission 
of @type is to be interpreted. No default value can be specified in the 
schema. No further action required.

§19.3.1.21 graphicFrame (@bwMode) (complex type: CT_GraphicalObjectFrame)

Chris Rae's proposed resolution is to add a default value "auto" to the 
schema. We agreed in the WG 4 face-to-face meeting on 2017-06-19 that 
the prose should not unnecessarily duplicate information in the schema, 
so no further action is required.

§19.5.1 anim (@by, @calcmode, @from, @to, @valueType) (complex type: 
CT_TLAnimateBehavior)

Chris Rae's proposed resolution is to add prose that specifies valid 
combinations of the attributes @by, @from and @to, and to change the 
schema to add default values "lin" and "num" for @calcMode and 
@valueType respectively. We agreed in the WG 4 face-to-face meeting on 
2017-06-19 that the prose should not unnecessarily duplicate information 
in the schema, so no further action is required.

§19.5.2 animClr (@clrSpc) (complex type: CT_TLAnimateColorBehavior)

Chris Rae's proposed resolution is to remove non-normative text, to add 
a note on color spaces, and to add a default value "rgb" to the schema. 
We agreed in the WG 4 face-to-face meeting on 2017-06-19 that the prose 
should not unnecessarily duplicate information in the schema, so no 
further action is required.

§19.5.3 animEffect (@filter) (complex type: CT_TLAnimateEffectBehavior)

Chris Rae's proposed resolution is to add prose to indicate how omission 
of @filter is to be interpreted. No default value can be specified in 
the schema. No further action required.

§19.5.4 animMotion (@origin, @path, @pathEditMode, @ptsTypes, @rAng) 
(complex type: CT_TLAnimateMotionBehavior)

Chris Rae's proposed resolution is to add prose to indicate how omission 
of @ptsTypes is to be interpreted, and to change the schema to add 
default values "parent", "" (null string), "relative" and "0" for 
attributes @origin, @path, @pathEditMode and @rAng respectively. We 
agreed in the WG 4 face-to-face meeting on 2017-06-19 that the prose 
should not unnecessarily duplicate information in the schema, but no 
default value for @ptsTypes can be specified in the schema, so additions 
to the prose are needed. We agreed to remove quotation marks around 
"Auto" in the added text. However, Murata-san has pointed out that, if 
omission of @ptsTypes implies Auto behaviour, value "A" is in effect the 
default value of the attribute. The prose already indicates that the 
value "A" implies Auto behaviour.

ACTION REQUIRED: Either change the schema to add "A" as a default value 
for @ptsTypes or, if we are uncertain about this, refer to the 
PowerPoint team for further clarification.

§19.5.5 animRot (@by, @from, @to) (complex type: 
CT_TLAnimateRotationBehavior)

Chris Rae's proposed resolution is to add prose that specifies valid 
combinations of the attributes @by, @from and @to. No default values can 
be specified in the schema for these attributes. No further action required.

§19.5.6 animScale (@zoomContents) (complex type: CT_TLAnimateScaleBehavior)

Chris Rae's proposed resolution is to add a default value "false" to the 
schema. We agreed in the WG 4 face-to-face meeting on 2017-06-19 that 
the prose should not unnecessarily duplicate information in the schema, 
so no further action is required.

§19.5.22 cBhvr (@accumulate, @additive, @by, @from, @override, @rctx, 
@to, @xfrmType) (complex type: CT_TLCommonBehaviorData)

Chris Rae's proposed resolution is to add prose to specify valid 
combinations of the attributes @by, @from and @to, to improve the 
description of @override, and to indicate how omission of @rctx is to be 
interpreted. Chris Rae also proposes to change the schema to add default 
values "base", "none", "pt" and "normal" for @accumulate, @additive, 
@xfrmType and @override respectively. We agreed in the WG 4 face-to-face 
meeting on 2017-06-19 that the prose should not unnecessarily duplicate 
information in the schema, so no further action is required.

§19.5.28 cmd (@cmd, @type) (complex type: CT_TLCommandBehavior)

Chris Rae's proposed resolution is to add prose to specify that @cmd 
must be present when @type is present, and to change the schema to add 
default value "call" for @type. But, as Murata-san has commented, if 
@type has a default value, this would seem to imply that @cmd is 
mandatory, because the absence of @type is equivalent to @type being 
present with value "call".

ACTION REQUIRED: Either change the schema to make @cmd required or, if 
we are uncertain about this, refer to the PowerPoint team for 
clarification.

§19.5.33 cTn (@afterEffect, @bldLvl, @display, @dur, @evtFilter, @fill, 
@masterRel, @nodePh, @nodeType, @presetClass, @presetSubtype, @restart, 
@syncBehavior, @tmFilter) (complex type: CT_TLCommonTimeNodeData)

Chris Rae's proposed resolution is to add prose to indicate how omission 
of any of @bldLvl, @evtFilter, @fill, @masterRel, @nodeType, 
@presetClass, @syncBehaviour and @tmFilter is to be interpreted, and to 
change the schema to add default values "0", "0", "always", "true", 
"false" and "false" for attributes @presetSubType, @dur, @restart, 
@display, @afterEffect and @nodePh respectively. We agreed in the WG 4 
face-to-face meeting on 2017-06-19 that the prose should not 
unnecessarily duplicate information in the schema, so no further action 
is required.

§19.5.39 endSync (@delay, @evt) (complex type: CT_TLTimeCondition)

Chris Rae's proposed resolution is to add prose to indicate how omission 
of @evt is to be interpreted, and to change the schema to add default 
value "0" for attribute @delay. We agreed in the WG 4 face-to-face 
meeting on 2017-06-19 that the prose should not unnecessarily duplicate 
information in the schema, so no further action is required.
