My basic concern was about the consistent versions in the dependencies. Say, have a multiproject
with ~50 subprojects and ~10 of them use e.g. xstream. Using entities I change currently only
one single line in one file to upgrade all of this 10 subprojects for a new xstream version
and does not have to care about, if possibly someone added a xstream dependency to another
subproject I currently do not know.

Without entities I have in M1 to make all subprojects dependend of XStream to achieve the
same ... what about M2?
