Daniel,
I have considered the report. While I admit, that isRestriction() should
return true, I do also believe, that it is too dangerous to fix this in
0.4: The change would affect almost all class generating code in the
JaxMe core.
I suggest, that you file a bug report in Jira. We'll fix that in the
HEAD branch, after 0.4 is out.
