Hi Dan,

The text you want stricken is from the currently published Last Call
Working Draft, not from my proposed response. My proposal was to change
it to:

 > "Note that although owl:imports and namespace declarations may appear

 > declarations simply set up a shorthand for referring to identifiers.
 > They do not implicitly include the meaning of documents located at

Note that this makes it clear that other applications, such as the ones
you have built, are free to process the namespace documents. I hope this
text is more acceptable to you.

I will delay making any responses on the two imports messages until
we've had a chance to come to consensus.
