Sure. Or you could say the property has multiple values.
In some processing scenarios, it's useful to
to test a document against some form(s) I already
know something about, and get a boolean.
In other scenarios, it's more useful to get an answer to
to the question: "what is the name of the *principle*
representational form"? Then, if I, the processor, possess
a model of forms that includes predicates such as
"is-a-restriction-of" or "is-arch-form-mappable-to"
other forms, then I can make an informed decision on
how I might process it.

Either you misunderstood my question, or you might
reconsider using "document type" to name this property.
