100% agree, Anders.
Valentin, in fact the tgrp comes from RFC4094:
trunk-group = ";tgrp=" trunk-group-label
trunk-context = ";trunk-context=" descriptor
trunk-group-label = 1*( unreserved / escaped /
trunk-group-unreserved )
trunk-group-unreserved = "/" / "&" / "+" / "$"
So, the " is not definitely allowed.

But note that in this case the quote characters are part of the
attribute value which is almost certainly not what is wanted or expected
here.
