New description:

 For performance, it is worth storing the CREATERUNTIMEMAP response XML
 content (with templated placeholders for session/mapname/etc) in a 2nd
 level cache, so that subsequent CREATERUNTIMEMAP requests for the same Map
 Definition with the same parameters can just read from the 2nd level
 cache, bypassing the creation of a MgMap and rendering the response XML
 from it.

 Being a representation of a Map Definition, such cached items can be
 automatically invalidated if the original Map Definition has been updated
 in the repository.
