Namespace problem

I have a problem in applying xslt to my xml having default namespace as
well as additional namespace. So if I have an xml which looks like this.
<query xmlns="myxml.com"> <elem1>abc</elem1> </query> The above one
works fine. but, <query xmlns="myxml.com" xmlns:m="myxml.com">
<elem1>abc</elem1> </query> doesnt work with my style sheet.
