A kind of dependencies? :)

The first thought which comes to my mind is what some persons will 
reply. Something on the line:
	"Yes, but subdividing a Spec which will not be a big fat cat and that 
nobody will even try to implement at all. Example, look at the SVG 1.0 
Specification... etc."
So I would say something that will show the costs and the benefits.:

"""
Same introduction

* Costs:
	Too many divisions complicates conformance and can hinder 
interoperability by increasing the chances of conflict with other 
aspects of the specification (e.g., other subdivisions).  Requirements 
may be in multiple places and/or duplicative, making them more 
difficult to find and increasing the probability of conflict and 
misinterpretation.  Subdividing the technology increases the likelihood 
that implementations will implement different subdivisions and thus not 
interoperate

* Benefits
	Subdividing the technology in small units will be easier to implement 
individually. It will help to organize the structure of the technology.
"""

Though I guess the GPs are about the benefits but in the intro, it 
might be good to have as small reminder.

	XHTML Modularization and SMIL gives good examples.
