It was certainly not intended to be.
For one thing, they're a subset of what you can do in SGML. I think
it was hoped that XML could get by without the SGML mechanisms of Ee
(entity and) and so on to describe it, but the result has turned out
to have a number of flaws.
I don't see any problem with parameter entities themselves, only with
the way they are described in the spec.
