The only way you can do this within XML Schema 1.0 is to have a local element emphasis within the content model of web, whose own content model is a restriction of the content model of the global web element. Yes, that's not a very attractive proposition. In XML Schema 1.1 you can have the complex type of web contain <xs:assert test="not(.//web)"/> Michael Kay http://www.saxonica.com/ > -----Original Message----- > From: xmlschema-dev-request@w3.org > [mailto:xmlschema-dev-request@w3.org] On Behalf Of Mario Madunic > Sent: 20 August 2007 16:51 > To: xmlschema-dev@w3.org > Subject: redefining or restricting children of a predefined element > > > Any help with the following will be greatly apreciated. > > I would like to change the emphasis child of web to not > contain an instance of web itself.
