[mapserver-users] WFS and typename issue

[Pericles S. Nacionales]

The WFS 1.0.0 doesn't specifically say not to use spaces in a typeName
but all the examples don't contain spaces...  The space character always
causes problem as part of a parameter in web forms, it should be
avoided.  That said, if the solution is as simple as escaping spaces in
MapServer's GML output then maybe it should be done.

It's not just spaces either...  any special character could potentially
be problematic (and maybe a potential security hole).  So, yes, you
probably should tell the WFS service author that it's bad karma to put
spaces in typeNames and featureIDs. :)  Add underscores or remove spaces
if possible.
