You're not likely to have to deal with bug reports that say "I wrote
<?xml-schema books.xsd?> and Saxon ignored it." 

But I am. I'm concerned about the people who understand very little, and
there are lots of them. These people see an example on a web page and copy
it, guessing the semantics from the keywords used. We really need to avoid
creating such obvious usability traps: the XML space has far too many of
them already.
