The DTD and schemas of released file formats shall be stored on the ASAM web server. Each file instance is required to supply a reference to the governig schema or DTD by an appropriate DOCTYPE declaration. By this, CDF instances are required to be valid XML documents.
XML schema as well as DTD is not strong enough to specifiy all details. Therefore it is recommended also to use Document Content Information. References to the matching DCI's is kept in the element <matching-dcis>.
Hint
There are not many XML tools around which really support namespaces. It is therefore recommended not to request a namespace-attribute. In conjunction with a general ASAM-XML strategy, this item should be worked out.
