If a namespace is specified, it must be one of the following values: ##any - Elements from any namespace can occur (default).<br>##other - Elements from any namespace outside the target namespace of the parent element can occur.<br>##local - Elements not qualified by a namespace can occur.<br>##targetNamespace - Elements from the target namespace of the parent element can occur.<br>A list of {URI references of namespaces, ##targetNamespace, ##local} - Elements from the namespaces listed, separated by spaces, can occur. The list can include URI references of namespaces ##targetNamespace and ##local.
processContents Optional. An indicator specifying how an application or XML processor should validate the XML document with elements specified by the any element. If the processContents attribute is not specified, it defaults to strict. If specified, it must be one of the following values: strict - The XML processor must obtain the required schemas and must validate all elements from these namespaces. (default)<br>lax - Same as strict; however, no errors occur if the schema cannot be obtained.<br>skip - The XML processor does not attempt to validate all elements from the specified namespaces.
