perfsonar development work

[Jochen Reinwand <>]

Hi Maxim,

This namespace stuff is normally handled by the XML library used for XML 
handling, since this behaviour is standardised by XML.

I can only speak for our Perl based services: We are using XML::LibXML, the 
Perl interface to libxml, the standard OpenSource XML library. Not only for 
performance reason we implemented SOAP support on our own and the complete 
XML message received via HTTP (including SOAP Envelope) is one LibXML DOM 
object. Therefore there should not be any problems with the namespace issues 
you mentioned and similar ones.

greetings,
Jochen
