updates to vo-dml spec

[Gerard Lemson]

Dear All
I have updated the docx and pdf versions of the VO-DML spec on volute (links
below).
I have fixed typos discovered by Florian and tried making at least some of
the comments on the utypes spec less offensive following the email
discussion with Francois. No doubt this is not the end of it. Please comment
on the text and also watch the comments page at
http://wiki.ivoa.net/twiki/bin/view/IVOA/VoDmlWGComments where I try to log
individual comments.

Cheers
Gerard
