DR-09-0048: WML, Fonts: Panose-1 classification mechanism missing

[Shawn Villaron]

Based on today's teleconference, here is the complete response to the defect report.  I believe that we can move this to LAST CALL and flag it for COR1:

DR 09-0048 - WML, Fonts: Panose-1 classification mechanism missing
Part 1, §17.8.3.13 will be updated as follows:
17.8.3.13        panose1 (Panose-1 Typeface Classification Number)
This element specifies the Panose-1 classification number for the current font using the mechanism defined shown in §4.2.7.17 of ISO/IEC 14496-22:2007. This information can be used as defined in font substitution logic to locate an appropriate substitute font when this font is not available. This information is determined by querying the font when present and shall not be modified when the font is not available.
If this element is omitted, then no Panose-1 information is available.
[Example: Consider the following information stored for a single font:

<w:font w:name="Times New Roman">
  <w:panose1 w:val="02020603050405020304" />
  ...
</w:font>
The panose1 element specifies its Panose-1 number via its val attribute value of 02020603050405020304. end example]
Parent Elements

font (§17.8.3.10)


Attributes

Description

val (Value)

Specifies the Panose-1 classification number for the font, stored as a series of two digit hexadecimal encodings of each digits of the Panose number.

[Example: Consider the following information stored for a single font:


<w:panose1 w:val="020F0603050405020304" />

The val attribute specifies that the digits in the Panose-1 number are: 2,15,6,3,5,2,3,4. end example]

The possible values for this attribute are defined by the ST_Panose simple type (§22.9.2.8).


[Note: The W3C XML Schema definition of this element's content model (CT_Panose) is located in §A.1. end note]

Greetings,

This defect report suggests that our current reference to the Panose 1 classification number is invalid.  We currently refer to section 4.2.7.17 of ISO/IEC 14496-22:2007.  I don't have access to this document.  Does anyone, and if you do, would you mind looking this up for me?  I'd like to know if we simply have the reference wrong ( e.g., the wrong section ) or if the referenced document is in error.

Thank you,

shawn
