[XOM-interest] Memory Sizes

[Elliotte Rusty Harold]

Before the release of 1.2.11 I'm thinking about backing out the
experimental limits on document memory sizes; that is, billion laugh
protection.

As best I can tell this doesn't truly work. It will catch some
problems, but can be bypassed by a clever attacker. I'd rather not
provide a false sense of security, and I think this can be better
addressed at the parser level using techniques like
XMLConstants.FEATURE_SECURE_PROCESSING

Any thoughts?
