Hi Timyothy,
First of all, the traceBlock as defined in the specification isn't
implemented yet as far as the evaluation engine is concerned. As for the
"id" attribute ... well this might be yet another issue of the spec.
As for extending MTL with Java defined external functions, this is
something we're thinking about but it clearly isn't a priority since we
need to fully implement the specification itself before thinking about
extending it. You're stuck with macros/queries for now :(.

Dear Laurent,
so, if i understand it right, it is so, that i have no possibility to get an
element's id? But, to prevent missunderstaning, i don't need the trace block
of the spec. I just need the access to the ids.

Hi Timothy,
AFAIK, there is no way to get the XMI ID of an element other than to get
it directly from the XMIResource reference. That can only be done in
Java and we do not provide a way to define custom operations in MTL as
yet (again, this will most probably evolve in the future).
However, if what you seek to obtain is not the XMI ID but rather the "ID
attribute" of an EClass, you can do so by iterating over all of its
attributes and selecting the one for which attr.isId() returns true.
