  Potential problems, intentionally left vague are how to deal with changed metadata files: should the !MdCreator and !MdCreationDate be adjusted? If yes, how persistent is the !MdSelfLink? As the metadata is created during the archiving state of a resource, potential updates are currently not dealt with.

+TODO: Include support for attributes as local extensions
+
+Accepted proposal by Twan & Menzo (2014-11-20 by e-mail to the members of the CMDI taskforce):
+
+* Allow attributes of a foreign namespace (i.e. not the general CMDI namespace) anywhere in the Header, Resources sections and on the 'Component' element (but not on any of its children) of a CMDI record, i.e. a profile instance
+* This is achieved by modifying the component specification to XSD stylesheet
+* There will be no consequence for existing components, profiles or records
+* The change will be part of both CMDI 1.1 and CMDI 1.2
+* The first application of this extension will be at TLA with the 'lat:localURI' attribute on ResourceRef elements 
+
+Additional formal constraints proposed by Oliver:
+
+These local attributes
+a) MUST be ignored by tools that don't understand them (or don't want
+    to deal with them) and therefore MAY be removed during processing
+b) the Namespace-Name MUST NOT contain fragments of official CLARIN
+    namespaces, i.e. don't start with the "http://www.clarin.eu",
+    "http://clarin.eu", etc.

 ==      The resources section ==
 The resources section in a metadata file list all information relevant for the individual resource, but does not describe the resource as such. The description is part of the components, the resource section provides the location of the resource or its parts if it consists of more than one, provenance information on the resource, information on the relation between the parts of the resource, if applicable and information of a greater body the resource is part of, also if applicable.
