[DAS2] stylesheet question

[Andrew Dalke]

I'm adding the DAS1 stylesheet information to the spec.
I don't want to change the data model that much.

I have a few questions about the existing DAS1 stylesheet.

In the text glyph definition there is a <STRING> element which
I assume is the string to use for  the label.  There is also a
<LABEL> attribute, which if "yes" says

     Whether the glyph should be labeled with its name, as dictated
     by the <FEATURE> label attribute in the DASGFF document.

I thought that meant either the label is given in the stylesheet
or the label comes from the glyph name.  But there are examples in
the sample_stylesheet which say

       <TYPE id="primer_left">
         <GLYPH>
           <TEXT>
             <FGCOLOR>purple</FGCOLOR>
             <FONT>helvetica</FONT>
             <FONTSIZE>8</FONTSIZE>
             <STRING>l</STRING>
             <LABEL>yes</LABEL>
           </TEXT>
         </GLYPH>
       </TYPE>

What happens in this case?



I noticed the section "Glyphs and Groups"

>          </BOX>
>       </GLYPH>
>    </TYPE>

>    <TYPE id="utr">
>       <GLYPH>
>          <BOX>
>             <BGCOLOR>blue</BGCOLOR>
>          </BOX>
>       </GLYPH>
>    </TYPE>
> </CATEGORY>
>
> <CATEGORY id="group">
> <TYPE id="transcript">
>    <GLYPH>
>       <LINE>
>          <FGCOLOR>black</FGCOLOR>
>          <LINE_STYLE>hat</LINE_STYLE>
>       </LINE>
>    </GLYPH>
> </TYPE>
> ...
>

Does anyone support this?

Should be be supported in DAS2?

If so, where does the between-feature style information go?
