Think of it from a programming language perspective:

class doc:
	title: string
	published: date
	authors: list of string
	text: list of (para|list|img)

The authors property is unordered with respect to the other properties
but its domain is ordered. The *list of authors* is metadata for the doc
object.

In grove land we allow a single, particular property to be labeled as
the content property. In this case it would be the "text:" property. In
a language like Python, you would navigate "regular (metadata)"
properties like this:

doc.publisher.address.street

and content properties like this:

doc[5][3][2][4]

In the former, the name is significant. In the latter the position is
significant. All of this is explained at:
