Eddie, The documentation element can have any element(s) from any namespace as children, as well as any subtree below that, due to processContents='lax' shown below. You would not have to escape the children of <documentation> in order to be valid. See: http://www.w3.org/TR/xmlschema-1/#element-documentation ..snipped from the schema 4 schema: <element id='documentation' name='documentation' xmlns:x='http://www.w3.org/XML/1998/namespace'> <complexType mixed='true'> <sequence maxOccurs='unbounded' minOccurs='0'> <any processContents='lax'/> </sequence> <attribute name='source' type='uriReference'/> <attribute ref='x:lang'/> </complexType> </element> -----Original Message----- From: Eddie Robertsson [mailto:eddie@allette.com.au] Sent: Wednesday, February 07, 2001 11:05 PM To: Sean B.

I had a look at the different schema documents involved and I found a couple of things that could cause your errors. The first thing I noticed (in xhtml.xsd and some others) was that you have elements inside your <documentation> element. I don't think you're allowed to have xml content within a <documentation> element but you can solve it by using the escaped '<'. E.g. <documentation> <div xmlns="http://www.w3.org/1999/xhtml"> <h1>XHTML Simple 1.0 XML Schema</h1> </documentation> would become: <documentation> <div xmlns="http://www.w3.org/1999/xhtml"> <h1>XHTML Simple 1.0 XML Schema</h1> </documentation> I also noticed that you're using the "http://www.w3.org/1999/xhtml" targetNamespace for all the schemas. Since you're using the "http://www.w3.org/2000/10/XMLSchema" namespace as default namespace for all schemas you need to qualify all your references to types and elements/attributes you define with the "http://www.w3.org/1999/xhtml" namespace. E.g. (in Common.xsd) <attributeGroup name="Core"> <attributeGroup ref="id"/> <attributeGroup ref="class"/> <attributeGroup ref="title"/> </attributeGroup> should be: <attributeGroup name="Core"> <attributeGroup ref="xhtml:id"/> <attributeGroup ref="xhtml:class"/> <attributeGroup ref="xhtml:title"/> </attributeGroup> where you have declared xhtml as xmlns:xhtml="http://www.w3.org/1999/xhtml" In block.xsd you also have the following attributeGroup: <attributeGroup name="pre.attlist"> <attributeGroup ref="Common"/> (should be xhtml:Common) <attribute name="xml:space"> <simpleType> <restriction base="xml:spaceX"> <enumeration value="preserve"/> </restriction> </simpleType> </attribute> </attributeGroup> I'm not sure what you're trying to do but it seems you're trying to restrict the values of the xml:space attribute and I don't think you're allowed to do that. > On another note (amatuer alert!), how you you denote the content model of > an element (link, img etc.) as being empty? Simple question, I know... but > I can't find the answer to it. <xsd:element name="Empty"> <xsd:complexType/> </xsd:element> Empty with an attribute: <xsd:element name="Empty"> <xsd:complexType> <xsd:attribute name="EmptyAttr" type="string"/> </xsd:complexType> </xsd:element> Hope this helps /Eddie > [1] http://infomesh.net/2001/xhtmls/xhtml.xsd > - XHTML Simple 1.0, Sean B.
