RE: [xml-dev] Schema Sanity Check

["Steven Livingstone" <s.livingstone@btinternet.com>]

So I tried the suggestion, but although MSXML 4.0 seems to have no
problem, the .Net version still seems to complain about the <b> element
having no schema :S

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>	
	<xsd:element name="name">
		<xsd:complexType>
			<xsd:sequence>
				<xsd:element name="first">
				   <xsd:complexType>
					<xsd:sequence>
						<xsd:any
namespace="##any" processContents="skip"  minOccurs="0"
maxOccurs="unbounded"/>
					</xsd:sequence>
				   </xsd:complexType>
				</xsd:element>
				<xsd:element name="middle"
type="xsd:string" />
				<xsd:element name="last"
type="xsd:string" />				
			</xsd:sequence>		
		</xsd:complexType>
	</xsd:element>
</xsd:schema>

<?xml version="1.0"?>
<name>
	<first><b>Steven</b></first>
	<middle />
	<last>Livingstone-Perez</last>	
</name>

Looking at the complex type definition for the ur-type[0] we note that
its {content type} has a particle whose {term} is a sequence whose
{particles} contains a single {term} which is wildcard with namespace
constraint set to any. 
 
In short, the content of a complex type of type xs:anyType is anything
from any namespace. However, the default value of processContents[1] for
a wildcard is strict meaning that a schema must be provided for each of
the elements [or attributes] that appear in the content model. 
 
So you can either provide a schema for all the extra elements and
attributes appearing as part of the <first> element or create a type
whose wildcard has processContents set to skip or lax and use that type
instead of xs:anyType.

	Do the following Schema and instance look ok?
	I keep getting an error saying the "<b>" elements are not
declared, but
	the type if first is anyType so should this not be anything I
want??
	Tried using MSXML 4.0 and .Net Schema classes.
	
	<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";>

	                        <xsd:sequence>
	                                <xsd:element name="first"
	type="xsd:anyType" />          
	                                <xsd:element name="middle"
	type="xsd:string" />
	                                <xsd:element name="last"

	                </xsd:complexType>

	        <middle />
