Since you have had no public replies, I'll add my 2p. I am, like you, a
consumer of XLL and not an author, so I'm prepared to be shot down.

I think this can be done through the internal DTD subset. it DOES mean that
the parser has to act on the internal subset, but it needn't be validating.
<!ATTLIST FOO BAR ID #REQUIRED>
will force all FOO's to have BAR attributes (if validated). It will also
say to the non-validating parser 'if you find a <FOO BAR="baz"> then the
BAR is of type ID whether you have an external DTD or not.

XLL has no concept of words (it doesn't know what whitespace is). The only
two alternatives are:
- to select a character
- to position an inter-character 'cursor'
I suspect the former would get most votes.
Note that to highlight using pure XLL would require '..' at present. I
to highlight the word 'jim'
Is this how other see it?

This is a very important question. I have asked it on XML-SIG - we'll see
what the gurus think. It is now legal to write:
<FOO HREF="a.xml" href="b.xml" Href="c.xml">
Inconsistency in examples of XML is rife :-) We need this cleared up quickly.

BTW it has been very quiet about XLL for the last 2 months or so. Is anyone
other than me implementing the draft?
