XPath question

Hello,

I'd like to create one schematron template that treats the same element
differently based on the presence of a child.  If the element has a certain
daughter, there are two validations.  If not, the same element has more
validations.  But I don't seem to be able to create a <rule> element
containing a 'not', and I can't think how else to do this.  Can anyone help?

<rule context="PUB-ENTRY/BIB/NOTICE[@WITH-DOCUMENT='NO']"> is fine
<rule context="PUB-ENTRY and not(BIB/NOTICE[@WITH-DOCUMENT='NO'])> throws an
error
<rule context="PUB-ENTRY"> + <rule
context="PUB-ENTRY/BIB/NOTICE[@WITH-DOCUMENT='NO']"> incorrectly runs all
validations

Thanks in advance!
