Hi all,
These days I'm playing with schemas and SOM from MSXML. To learn it I used
the excellent tutorial from Mr.Costello:
http://www.xfront.com/xml-schema.html. while working through the labs I
stumbled upon a problem with substitutionGro up-s (Lab 9).
Below you can find both the schema and a sample document to test it.
Unfortunately, MSXML doesn't like the document and ends up with an error:
"### <guarantee>life time warranty</guarantee>(11) error: Element content
is invalid according to the DTD/Schema." Can someone please take a look at
it and comment on the problem. May be I am doing something wrong here or
may be someone can confirm that this is MSXML validation bug.
Thank you!
Val Melamed
