Hi Bob,

I wrongly presumed that Dave added code for the WFS Layer, but it was
for the WFSProtocol. I found out when making a start on adding a WFS
example.

It seems to me then that the WFS implementation is yours. Would you
feel comfortable adding that to the codebase? If so, then I will add
you as a developer. Alternatively, you can send me the files and I
will make sure they make it into the codebase promptly.

Coming monday I hope to have a bit of time to see what needs to be
done to get a new GWT-OL release out shortly and it would be nice if
the WFS stuff can be in it.

Greetings,
Edwin
