[Andrew Grimshaw] This is exactly what the extensibility point is for, so
that extra information can be agreed upon and profiled without requiring a
new function to be defined every time an optional parameter is desired.
Thus, a profile can be constructed along with a conformance claim and a
service can advertise which profiles/conformance claims it supports.

[Andrew Grimshaw] There is no ambiguity around the ActivityDocument. As
specified it has a JSDL document embedded. Anything else may or may not be
used by the service.
