What makes you think that the [schema documents] property is any more "required" than [schema components]?  The REC says that [schema documents] can be empty as well:

	A (possibly empty) set of schema document information items,
	with properties and values as follows, for each schema document
	which contributed components to the schema, and whose targetNamespace
	matches the sibling [schema namespace] property above (or whose
	targetNamespace was ·absent· but that contributed components to
	that namespace by being <include>d by a schema document with
	that targetNamespace as per Assembling a schema for a single
	target namespace from multiple schema definition documents (§4.2.1)).
