I tried moving the params to the top and running your
xml/xsl files against a few processors -- Saxon, Xalan,
and XSLTC. They all complained about the AVT in the
select attribute. On reading the XSLT spec, it actually
implies in Section 10 that an Attribute Value Template
is not legal in the "select" attribute of a Sort element, while
is it legal in the "order" attribute. When I hard-wired the
element name to 'COLUMN1' in the "select" attribute, all
the processors now were happy.
I used Xalan from the command line after updating
today's build. So I'm confused as to how it works for
you now by just moving the params to the global position.
Not that I'm not happy for you. Now I'm not sure if there
is a deficiency in XSLTC in not handling an AVT in the
select attribute -- if Xalan does.
