[webservices] Beta release of ws-station, including a new StationXML schema

[John D. West]

Hi.

I don't like to be the one to slow down progress, but I have oral exams on
April 2 and have no time before them to test the beta or update EMERALD to
handle the new schema. Is there any chance we can put this one off for a
week or two?

Many thanks,
