Hello Karl,

Many thanks for your comments. Just a few notes from myself:

Why didn't you submit the comments one-by-one with the form?
Did you think it was too difficult? Was it not clear that
that's what should be done? Did you just want to save time,
because you already had all the text typed up?
[I ask because the form is an experiment, and any feedback
is appreciated.]

Actually, the source is in XML, so XSLT can be applied to XML directly :-).

Which one?

Binary tests are very difficult in many case, or have to be worked
out individually for each spec (e.g. XML, CSS,...)

This would be wrong because there are also multiple phonemes - one character
and multiple phonemes - multiple characters. Excluding the one-to-one case
looked easier.

I think it can be [S/I/C]. Specifications don't store or interchange
data, but they specify how it's done.

Yes. But 'possible meanings' -> 'meaning'.

Thanks for the comments.     Regards,    Martin.
