    	<xsd:attribute name="format" type="xsd:string">
    		<xsd:annotation>
    			<xsd:documentation>The format is a required attribute of type `string`. It indicates the file type of the 
*Content* element. The values of the `format` attribute fall in two categories. Either the
`format` denotes one of the COMBINE standards, in which case the format will 
begin with its `identifiers.org` url. Otherwise the format will represent a MIME type.
Using identifiers.org allows to unambiguously define the COMBINE standard, and even its level and version.
For example, the identifier:

    http://identifiers.org/combine.specifications/sbml 

would denote the *Content* element as being encoded in the SBML format. That is 
usually sufficient, as tools supporting one level of SBML usually support others as
well. However, if the software exporting the COMBINE archive wanted to be more precise, it could specify that it is an SBML Level 2 document with

    http://identifiers.org/combine.specifications/sbml.level-2

or even declare its Version with
     http://identifiers.org/combine.specifications/sbml.level-2.version-3
