Re: [xsl] Why does this XPath expression work fine when run inOxygen but fails when used in an XSD 1.1 assert element?

Your original error message said,
Assertion evaluation ('*[local-name(.) eq
'style']/following-sibling::comment()[1]/starts-with(., '[if gte mso
9]><xml>')') for element 'head' on schema type 'headType' did not succeed.

(This looks to be a message generated by Xerces validator)

What Mike has written above, is also supported by Xerces, i.e with an user
option assertion XDM trees can contain comments and PIs. I think that,
Oxygen XML IDE has an option to toggle this XSD validation feature.

Of course, you may also use Saxon if you wish.
