DIWG Response
=============

DIWG agrees that access to metrics based on font size is desirable. 
However, the starter set functions merely replicate the capabilities of 
CSS Media Queries as currently defined. Since that is their declared 
purpose, it would be inconsistent to extend them.

However, as is noted in the response to comment WAI-1, DIWG will expand 
the set of XPath functions to include more general mechanisms for access. 
Such functions would be capable of retrieving font-size based information 
if that is available in the delivery context.

So, while DIWG declines to extend the starter set functions, we believe 
that other facilites will make this information available to authors if it 
is available within the delivery context.
