Military terminology, titulature, religious indicators, social/political/economic vocabulary are not currently being tagged in a specific way.
One way of extracting this terminology is through the vocabulary, using the @lemma attribute of the <w> element.
Another way could be using the <rs> element and the different values of the @type attribute could be similar to the categories used by the EDH. A @key or a @ref attribute could point to an authoriry list.
