In namespace processing, the prefix is irrelevant.
But ... neither of the above is valid from a W3C Schema perspective since
the "element" element of a schema expression needs to be in the W3C namespace.
In XML documents the following are equivalent:
<ns1:method2request
xmlns:ns1="http://biryani.med.yale.edu:8081/axis/services/GetXSLIM"/>
<ns2:method2request
xmlns:ns2="http://biryani.med.yale.edu:8081/axis/services/GetXSLIM"/>
Note that nothing needs to exist at the URL of the URI ... a namespace
aware application does *not* attempt to dereference or locate *any* piece
of information at the address represented by the string.
I hope this helps.
