Hi Khaled, The Subject Scheme DITA Map can be used to impose controlled values on attributes which are already defined as allowed in the DITA content. So if you define in the Subject Scheme Map an attribute (in your case "p-doc") as having certain values this does not mean that the attribute is recognized by the DITA DTDs associated to your topics and maps. So you would still need to create a DTD specialization to add a new DITA attribute. Please see Eliot Kimber's excellent tutorial link below:

Hi

I’m running an elementary Subject Scheme test to learn how to use it later for producing a full taxonomy, followed the simple instructions at http://www.oxygenxml.com/doc/ug-editor/topics/subject-scheme-map.html.

However, when using the attribute defined in the subject scheme map, and although auto completion recognizes its defined values; I get the error: Attribute "p-doc" must be declared for element type "p", where “p-doc” is the ‘attributedef’ name within the ‘enumerationdef’ element.

Subject scheme file validates well and ditamap file references the subject scheme file. The three files are attached.

Would appreciate any directions about this.

Khaled
