Except, of course, that the logic of the design, as I have
understood it so far, relies on an inference something like:
The author did not point to this transformation from
the document, nor did the namespace owner point to this
transformation from the namespace name.
Therefore, the transformation is not a faithful rendition
of the author's intentions.
The rest of your note may be trying to clarify the notion of
authority in such a way as to make me see that this is not
the required inference; I need to read your note more carefully
to see.

(Side note.) Not quite true: XSLT transformations can take
invocation-time parameters, and can be affected by documents
other than the main input, by use of the document() function.
