Re: PIs considered harmful Was: XML-SW, a thought experiment

This anti-PI stuff is all fine in theory, and probably if we thought it
through enough we could come up with an alternate theory in which they
are just fine (I feel like I did that a year ago, and the year before
that, and the year before that). But the main point is that they are
extremely useful in *practice* and in my mind, that trumps theory.

In theory this is a problem. In practice I've never seen it. Either way,
it would be easy to define such a mechanism. xmlns="..." is really
sufficient.
