I am trying to find how to validate a xml file with two schema files where one schema file cust.xsd allows addition of elements from another schema cust1.xsd by using xs:any wildcard.

cust.xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:cust="urn:25hoursaday-com:customer"
targetNamespace="urn:25hoursaday-com:customer" elementFormDefault="qualified">
<xs:element name="Customer">
<xs:complexType>
<xs:sequence>
<xs:element name="FirstName" type="xs:string" />
<xs:element name="LastName" type="xs:string" />
<xs:any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded" />
</xs:sequence>
<xs:attribute name="customerID" type="xs:integer" />
<xs:anyAttribute namespace="##any" processContents="skip" />
</xs:complexType>
</xs:element>
<xs:element name="PhoneNumber" type="xs:string" />
<xs:element name="FrequentShopper" type="xs:boolean" />

<xs:complexType name="Element-0" abstract="true">
<xs:choice>
<xs:element name="untitled1"/>
<xs:element name="untitled2"/>
</xs:choice>
</xs:complexType>
</xs:schema>

cust1.xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:addr="urn:25hoursaday-com:address"
targetNamespace="urn:25hoursaday-com:address" elementFormDefault="qualified">
<xs:element name="Customer">
<xs:complexType>
<xs:sequence>
<xs:element name="Address" type="xs:string" />
<xs:element name="City" type="xs:string" />
<xs:element name="State" type="xs:string" />
<xs:element name="Zip" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

and now the cust.xml that needs to be validated against both cust.xsd and cust1.xsd
<cust:Customer customerID="12345" numPurchases="17"
xmlns:cust="urn:25hoursaday-com:customer"
SchemaLocation="file://c:/per/Schemas_nn/test/cust.xsd"
xmlns:addr="urn:25hoursaday-com:address"
SchemaLocation="file://c:/per/Schemas_nn/test/cust1.xsd">

<cust:FirstName >Dare</cust:FirstName>
<cust:LastName >Obasanjo</cust:LastName>
<cust:PhoneNumber >425-555-1234</cust:PhoneNumber>

<addr:Address>2001 Beagle Drive</addr:Address>
<addr:City>Redmond</addr:City>
<addr:State>WA</addr:State>
<addr:Zip>98052</addr:Zip>
</cust:Customer>
Gives error: The attribute 'SchemaLocation' is already used in element 'cust:Customer'

My problem is how to tell the xml document that it has to validate against two schemas by pointing to two different locations of each schema

I really appreciate your help!

First, which version of Stylus Studio are you using?

You are placing two SchemaLocation attributes on the root element, and this is not valid XML. In order to bind a single XML with more than one schema you should use this syntax:

<cust:Customer customerID="12345" numPurchases="17" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:25hoursaday-com:customer file:///c:/per/Schemas_nn/test/cust.xsd urn:25hoursaday-com:address file:///c:/per/Schemas_nn/test/cust1.xsd">

The xsi:schemaLocation contains pair of strings, the first to define the namespace schema and the second to locate the XMLSchema file for that namespace.
You can let Stylus build the proper attributes by using XML | Associate XML with Schema multiple times.

Hope this helps,
Alberto
