This is a really nice summary of the problem, I think. Identification
comes before explanation, and the two look like they are combined at present.
One additional aspect I would add is that Joe Developer doesn't appear to
be the only person making statements about what namespaces mean based on
what they expected to see in the spec.
The XML-URI discussions this summer had to deal with namespace-oriented
expectations made explicit in other (non-Recommendation, but apparently
axiomatic) W3C documents [1] [2] [3].
For example (from [1]):

Recent activity by the XML Schema Working Group [4] seems to confirm this
reading.
