Matt DeBoer commented on MNG-3556:
----------------------------------
It has been mentioned that the reason for not supporting XML entities is that
it provides capability to create a non-self-contained pom.
That argument doesn't apply to internal XML entities. Is there some reason
support for these was thrown out along with external entities?
