XsltResponseWriter date handling

[Erik Hatcher]

I've done exorcisms to eradicate what I once knew about XSL from my  
head, but now I find myself interested in playing some games with the  
XsltResponseWriter for pragmatic "the desired output is  
straightforward XML" reasons.  I need to take a Solr date value in  
"2008-10-30T03:28:10.000Z" format and output it as a GMT formatted  
date like "Oct 30 2008 03:28:10 GMT-0600".

Anyone got the incantation handy to make such a conversion in XSLT?
