What I said was ambiguous was what the implications of that italicized
(non-normative) paragraph were.  I take it you are saying that it's
unambiguous in that paragraph that DW_FORM_data* interpretation is
unspecified, and therefore unambiguous that the paragraph implies nothing
about that interpretation.  Is that what you meant?

You just said that the standard does not specify an interpretation.
