Little correction:

The description of <#Describes> is as follows:

<#Describes> <#Type> <#Property>.
<#Describes> <#Domain> xsd:anyURI .
<#Describes> <#Range> xsd:anyURI .
<#Describes> <#Label> "Describes" .
<#Describes> <#Comments> "A predicate that associates an entity of type: 
Document, with a Description Subject." .
