There's a common trick to prevent bots scanning sites and collecting
email addresses
which assumes the screen scraper can't read xml or html syntax which is less and
less common, but anyway
standard xslt 1 doesn't honour doe in attributes, saxon has an extension
to allow this, I'm not sure which engine you are using from php
(libxslt? sablotron?, ...) I don't see anything in exslt but perhaps
your processor has a specific extension cf
