Check the element for the following OPC compliance rules:

Rule M4.2: A format consumer shall consider the use of the Markup Compatibility namespace to be an error.

Rule M4.3: Producers shall not create a document element that contains refinements to the Dublin Core elements, except for the two specified in the schema: <dcterms:created> and <dcterms:modified> Consumers shall consider a document element that violates this constraint to be an error.

Rule M4.4: Producers shall not create a document element that contains the xml:lang attribute. Consumers shall consider a document element that violates this constraint to be an error.

Rule M4.5: Producers shall not create a document element that contains the xsi:type attribute, except for a <dcterms:created> or <dcterms:modified> element where the xsi:type attribute shall be present and shall hold the value dcterms:W3CDTF, where dcterms is the namespace prefix of the Dublin Core namespace. Consumers shall consider a document element that violates this constraint to be an error.
