Yes, you're right. validate_schema is listed as a method of
XML::Document but never appears in the method description. Unless
there is a ruby syntax quirk I'm not aware of.
I did see the validate_schema method in the top right hand methods
list, but it says validate_schema(XML::Document), rather than
validate_schema(XML::Schema) which confused me somewhat.
Unfortunately I've just found out that xmllint doesn't insert missing
default values. Well, at least I can validate now.
Thanks
