[mapguide-users] Generating tiles for google maps

I have have been trying to modify my map using mapagent. I have exported
the resource content and then edited the coordinate system to use the
WKT representation of the projection. I can not seem to get past an
error in the Metadata tag:
'Parser message: In element Metadata: Can not have element children
within a simple type content. '
If I remove the metadata, I get an exception error when trying to open
the map in Studio. My XML is below:
+a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0
+units=m +nadgrids=@null +wktext +no_defs"]]
Is there something obvious that I am missing?
Thanks for the help!
