Richard,

1) RXP is a great tool. I like it very much. Please do not take it as a personal
offense, I am discussing XML Namespaces recommendation.

2) If the latest version of RXP says that Attribute name :b has empty prefix, then
in my opinion it is still wrong, since there is no thing like prefix for :b, since :b
is not a QName, and a prefix is a feature of a QName.

3) My version of RXP is 1.3, I downloaded it yesterday by following a link from your RXP
page. I've just went there and logged in via ftp, and found that there are pre-releases
of 1.4; and it is great that RXP now recognizes such documents as non-well-formed, but
the message should still be different, as it is not a QName, not an empty prefix.

My point is still the recommendation is faulty, not that an implementation is. I used the
example just to illustrate it.
