The entire text data content of the node (in parse order) is the text from
the source tree.
To illustrate this, I've written a stylesheet for both XT and IE5b2, and
the results are noted below.
Interestingly, MSXSL accepts no specification of a match attribute and
appears to match on everything when no value is specified, yet Appendix A
of the WD requires the attribute:
<!ELEMENT xsl:template %template;>
<!ATTLIST xsl:template
match %pattern; #REQUIRED
priority %priority; #IMPLIED
mode NMTOKEN #IMPLIED
%space-att;
>
Looking at the XT and IE5b2 results, I see that both are correctly
interpreting that the value-of is calculated from of *all* of the
subelements of the node, not triggering template rules on subelements (see
element <testb>).
Also note that with no match attribute IE5b2 will process *all* nodes (the
output shows the processing of the XML Declaration), while with the
match="*" attribute the WD Production [12] is documented that "*"
represents elements, so therefore the IE5b2 no-attribute interpretation
can't be documented as "*".
I hope this helps.
