4 largely depends on your definition of "easy".  5 is where things
rapidly get aggravating.  A lot of the chaos on point five crept in late
in the process, with standalone and the non-validating parsers can
ignore external subset business.

I have to admit that XML 1.0, flaws and all, makes me feel all warm and
