Again, the mere *provision* of typing metadata does not prevent such reuse.
However, if *standard tools* assume that the metadata is sound, then
transgressive reuse may indeed be made difficult.  Obviously, purely lexical
tools are not affected, but tools based on XQuery/XPath2/XSLT2 will not
be purely lexical in this sense (whereas XPath1/XSLT1 are).

Hard to do when the standards are still fluid and the corresponding tools
not yet in wide use.
