    <rdfs:comment>While a Document can contain structured data, it normally has explanatory material included, which would cause it to therefore be considered semi-structured.  It is for this reason that there is no “contains” relationship from Document to Structured Data Resource. It is very important to separate Documents from Structured Data Resources because they are processed very differently. The difference between a Document and a Digital Data Resource, therefore, is that a Digital Data Resource can contained structured data.</rdfs:comment>

    >The “Identifier” attribute is described at an abstract level in order to be consistent with the abstract nature of the reference model. Therefore, there are no references to aspects such as identifier uniqueness, representation format, or similar. Implementations based on the DRM will introduce such aspects as needed according to their requirements.</rdfs:comment>
