Brett Porter commented on MNG-3556:
-----------------------------------
Matt: combination of lack of parser support at the time in conjunction with the
decision not to use it. My only thought at this stage some years later might be
tool support. Regardless, it would be far better to focus on shipping support
for more concise formats or ways to compose the model of other external
fragments in a generic fashion rather than relying on XML tooling specifically.
