HELP - Defining a schema with namespace

The following is the XML for which schema has to be defined. Can you please help me define a schema.I cannot use ‘:’ in the element name. I need the schema to be exactly similar to this.
Thanks a lot for the help in advance.

Hi

the point is that a single schema document only takes definitions for a single targetNamespace. Hence, a schema for multiple namespace must contain of multiple
schema documents which refer to each other using xs:import elements.
(xs:include composes schema documents for the same targetNamespace)

A very simple example looks as follows:

<xs:schema targetNamespace=“URI1” xmlns:p1=“URI1” …>
<xs:element name=“E1”/>
</xs:schema>

<xs:schema targetNamespace=“URI2” xmlns:p2=“URI2” xmlns:p1=“URI1” …>
<xs:import namespace=“URI2” schemaLocation="…"/>
<xs:element name=“E2”>
xs:complexType
xs:sequence
<xs:element ref=“p1:E1”/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Hope that helps
