Is there a set of rules or best practices about what to do with space
between words when you encode down to the word level? We have in one
project used space between <w> elements, and the parser respects
this, although it seems theoretically wrong. One could also deal with
the space at the processing level and have a rule to the effect that
a word element is followed by a space unless the content of the next
element begins with a punctuation mark, etc.
I'll be grateful for advice.
