[xsl] Fwd: Re: unable to dynamically set sort order

["bharat chintapally" <hydbad at hotmail dot com>]

Hi Dimitre:
           Thanks for your reply, when I read about the xsl:sort, it seems 
to me that for the select attribute we can specify an expression (this can 
be any xpath expression ?). Well if I tried that (I specifed the XPath 
expression as "/xx/yy/zz/sortColumn", it doesn't seem to be working.. And 
for the order attribute, I can only use the string "ascending | descending". 
I can't even use a variable.. This seems to be weird restriction. Why can't 
this values be evaluated when a template is applied. BTW what is an AVT-s 
are you talking abour data stru. AVT.

Thanks
