ok, but changing the xml for the map def blows away a tile cache

I would probably add the image format (two formats: normal and base layers), selection color, and meta tile factor to our current MapDefinition and then add a second "tile" MapDefinition to WebLayout and ApplicationDefinition.  As far as I know, both viewers render the base tiles as a separate div tag so it wouldn't be much work to point them at a different MapDefinition.

i'd guess i'd rather a 'meta' map definition (collection?), which
WebLayout and ApplicationDefinition consume,
rather than having dual implementations

yup i concur about the 2.2, how about a minor point release, rather
than letting this sit in subversion
out of the hands of users for a long time, like RFC60 did?

Just because Autodesk releases an annual MGE, doesn't mean MGOS has to

hence my suggestion for attributes in headers which requires no
changes to MapDefinition or LayerDefinition, I'm thinking
primarily about ability to tweak the meta tile factor per map whilst
protecting my precious tile cache
