Complete the list of expression attributes

[ndw]

parse.xsl checks for expressions in an ad hoc set of attributes:

<xsl:template match="@select[namespace-uri(parent::*)
                             ='http://www.w3.org/1999/XSL/Transform']
                     |xsl:if/@test
                     |xsl:when/@test
                     |xsl:evaluate/@context-item
                     |xsl:evaluate/@xpath
                     |xsl:template/@match
                     |xsl:group-by/@group-by">
  <xsl:sequence select="f:parse-expr(parent::*, .)"/>
</xsl:template>

That list should be made comprehensive.

Norm, xsl:group-by is a new element I haven't heard of :-)

I scanned the XSLT3 spec for all attributes that are either expression or pattern and the result is this:

@match (: xsl:accumulator-rule, xsl:key, xsl:template :)
@select (: many elements :)
@test (: xsl:assert, xsl:if, xsl:when :)
@use-when (: almost every element :)

xsl:accumulator/@initial-value
xsl:evaluate/@xpath
xsl:evaluate/@with-params
xsl:evaluate/@context-item
xsl:evaluate/@namespace-context
xsl:for-each-group/@group-by
xsl:for-each-group/@group-adjacent
xsl:for-each-group/@group-starting-with
xsl:for-each-group/@group-ending-with
xsl:key/@use
xsl:map-entry/@use
xsl:merge-source/@for-each-item
xsl:merge-source/@for-each-source
xsl:number/@value
xsl:number/@count
xsl:number/@from

[ndw]

Indeed, that should be xsl:for-each-group and the list probably should be made comprehensive!

OK, I forgot @select in my comment above, but added it now.

I am not sure, whether the list of all attributes of type expression and pattern are sufficient/comprehensive.

Thank you for the list. I'll try to get to this in the next little while, but there's a whole lot going on right now!
