perfsonar development work

Hi Jason,

Thanks for the pointers. Indeed there are a bunch of WSDL files in the
MDM subversion repository, including those for E2Emon. Roman pointed me
off-list to them as well (thanks, Roman!).

Unfortunately, while the message types are described, the message
content is not -- only the top level nmwg:message tag is described, not
the nmwg:data or nwmg:metadata tags, let alone the really interesting
tags and attributes. This means that even with a WSDL, one has to do a
lot of validation themselves, so it only helps me a little bit.

I was trying to understand if it is possible to extend the WSDL or if
NMWG is so flexible that this never gains anything useful. It indeed
seems easier to simply parse the XML myself -- like pS-PS and Sander's
code do.

Sander told me the same, but the difference is only sketchy to me yet.
This comments helps me, thanks!

Yup :)

Thanks,
