Normative status of XML primer?

The "Status of this Document" section of the XML Primer dated May 2, 2001 states
	It is a stable document and may be used as reference material or cited as a normative reference from another document. 
On the other hand, the "Abstract" section of the XML Primer dated May 2, 2001 states
	XML Schema Part 0: Primer is a non-normative document intended to provide an easily readable description of the 	XML Schema facilities ...
Also, section 1 "Introduction" of the XML Primer dated May 2, 2001 states
	The primer is a non-normative document, which means that it does not provide a definitive (from the W3C's point of 	view) specification of the XML Schema language. 
Is it not contradictory to say that a "non-normative document"  can be "cited as a normative reference from another document"?
