xsl behavior 2003-03-19 - By Santiago Pericas-Geertsen
Tim, Dimitry,
This looks like a problem in XSLTC. It is checking the context of an
xsl:attribute and trying to be smart as to whether is misplaced or not. The
requirement is for attributes to be output before children. The stylesheet
is OK, but in general a call to xsl:apply-templates *may* add children (e.g.
text nodes) to which an attribute cannot be associated.
Try commenting out line 142 in xsltc/compiler/XslAttribute.java and see
what happens (_ignore = true). Obviously, this heuristic must be revisited
(I think the warning is OK, ignoring the attribute is not).
