DR 09-0040: WML/DML: Complex scripts

[Arms, Caroline]

Chris,
I have no doubt that the "algorithm" addresses issues raised by this DR, but it's not clear to me that the precise question has been answered directly.  The DR mentions several specific sections that use the phrases "complex script characters" or "complex script contents [of a run]" with apparently different interpretations for the range of characters included.  Your proposed change to 17.3.2.26 certainly doesn't address that directly.

THE SECTION YOU PROPOSED ADDING THE ALGORITHM TO BEGINS BY DIVIDING CHARACTERS INTO 4 SETS:
17.3.2.26 rFonts (Run Fonts)
This element specifies the fonts which shall be used to display the text contents of this run. Within a single run, there can be up to four types of content present which shall each be allowed to use a unique font:
•ASCII (i.e., the first 128 Unicode code points)
•High ANSI
•Complex Script
•East Asian
The use of each of these fonts shall be determined by the Unicode character values of the run content, unless manually overridden via use of the cs element (§17.3.2.7).

[Aside: It might be helpful to provide the ranges that apply unless manually over-ridden.]

MEANWHILE
17.3.2.1 b (Bold)
This element specifies whether the bold property shall be applied to all non-complex script characters in the contents of this run when displayed in a document.

AND
17.3.2.2 bCs (Complex Script Bold)
This element specifies whether the bold property shall be applied to all complex script characters in the contents of this run when displayed in a document.

APPEAR TO DIVIDE THE CHARACTER UNIVERSE INTO 2 SETS

SO WHAT DO b AND bCs DO FOR High ANSI or East Asian as defined in 17.3.2.26?

This is just ONE of the examples raised in the DR.

I find myself wondering whether Shawn's earlier work on this DR might have addressed this, but it is not reflected in the DR Log.

I applied those edits to Chris' proposal when I added it to the log. Should I also be adding a language code for Chinese Simplified?
