[xquery-talk] Necessary whitespace

[Christian Grün]

Hi Benito,

These ones are valid:

> 3!(10---.)
> 12!(.div 3)

...and these ones are not:

> 12!(12 div.)
> 1<<a>2</a>
> 12 div-3
> 3!(12 div-.)

It would take some time to elaborate all the reasons for that (I would
surely need to look it up as well), but "12 div-3" is maybe easy to
explain: div-3 is also a valid name test and, thus, path expression.

Cheers,
Christian
