Question

How can you define an xsd element that can contain any number of properties with any name, any number of child elements with any name and text?

Is it just a matter of defining the following?

Answer 1

I found the answer:

You define the element as shown below:
<xs:element name="foo" type="fooType"/>

And then the type:
<xs:complexType name="fooType" mixed="true">
<xs:choice maxOccurs="unbounded">
<xs:any namespace="##any" processContents="skip" minOccurs="0" maxOccurs="unbounded"/>
</xs:choice>
<xs:anyAttribute namespace="##any" processContents="skip"/>
</xs:complexType>
