• Thread-topic: Schema Sanity Check

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:element name="name">
	                <xsd:complexType>
	                        <xsd:sequence>
	                                <xsd:element name="first"
	type="xsd:anyType" />          
	                                <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 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	        xsi:noNamespaceSchemaLocation="schema.xsd">
	        <first><b>Steven</b></first>
	        <middle />
	        <last>Livingstone-Perez</last> 
	</name>
	
	Thanks,
	Steven
