Re: Spec DTD

There are two customisations I would like to migrate from the XSLT spec area to use in the other specs:

(a) the ability to have a <var> element inside <code> for italicized code.

xsltspec.dtd lines 55-57

<!-- Allow a 'code' element to contain a 'var' element for italicised code -->

<!ELEMENT code (%tech.pcd.mix;|var)*>

Seen for example in section 6.5 of the XSLT spec.

(b) Custom rendering of <var> elements.

xslt.xsl lines 443-459

  <xsl:template match="var[matches(., '[A-Z][0-9]')]">
    <var>
      <xsl:value-of select="substring(., 1, 1)"/>
      <sub><xsl:value-of select="substring(., 2, 1)"/></sub>
    </var>
  </xsl:template>
  
  <xsl:template match="var[contains(., '/')]">
    <var>
      <xsl:value-of select="substring-before(., '/')"/>
      <sub><xsl:value-of select="substring-after(., '/')"/></sub>
    </var>
  </xsl:template>

  <xsl:template match="var[matches(., '[A-Z]''')]">
    <var><xsl:value-of select="translate(., '''', '&#x2032;')"/></var>
  </xsl:template>  

Allowing <var>A1</var> for A subscript 1, <var>A/i</var for A subscript i, and <var>A'</var> for A prime.

Seen for example in section 3.5.1 of the XSLT spec.

Any objections?

Section 2.5.6 of the XPath spec, for example, would benefit from similar treatment.
