Re: [xsl] My XPath mistakenly referenced an element that doesn't exist and I got no error message ... is this bad language design?

Even adding req() as a synonym for one-or-more() might be enough to 
encourage people to write req(Document)/req(foo) in order to get better 
diagnostics.

Why not just:

       req(Document/foo)


The finer-grained form would enable more precise diagnostics.

And they aren't equivalent: if there are two Document elements, only one of 
which has a foo child, one expression would fail and the other would succeed.
