- add size and xml formatter to apm parameter spec- add configurable xml formatter that is able to handle multiple entries and value-coding in attributes
- only variables in a non-top namespace survive session cleanup. The logic of the old code assumed that global variables survive the request-cleanup. now, the cached values is kept in the ::acs::* namespace
- the datatype of session_id in sec_session_properties should be the same as the sequence. Without this change, busy sites will run into a overflow (as we did a while ago).
