Elements from namespace other than target namespace (which is null)

XML Schema
Relax NG

Please, send all comments, bug-reports, and contributions to Jiri.Jirat@systinet.com. Thank you very much.

XML Schema keys: any, maxOccurs
Relax NG keys: anyName, except, nsName

1. XML Schema

The root element named "root" can have an arbitrary number of any elements from namespace other than the target namespace. The target namespace is null here. The "namespace" attribute will be set to value "##other". It will allow all elements which are from namespace other than null namespace.

Valid document

Invalid document
Element is from null namespace (the "target namespace") - that's not allowed.

Correct XML Schema (correct_0.xsd)

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" >

  <xsd:element name="root">
    <xsd:complexType>
      <xsd:sequence minOccurs="1" maxOccurs="1">
        <xsd:any namespace="##other" minOccurs="0" maxOccurs="unbounded" processContents="skip"/>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

2. Relax NG

The element "anyName" says that the attribute can have any name from any namespace. We will exclude all attributes from the null namespace ("target namespace") using the "except" and "nsName" elements.

Valid document

Invalid document
Element is from null namespace (the "target namespace") - that's not allowed.
