Ulinks to example URLs

Hey,

Does anyone process or markup ulinks differently if they point to
invalid (example) URLs? There's currently a push from our Production
department to not have ulinks to obviously example sites like <ulink
url="example.com/some_complex_path/foo/bar.xml"/> rendered as PDF
links. I have my own opinions, but....

Good style for marking up/displaying ulinks that aren't real?


Thanks,
Keith
