I did some of my homework re HTML5.  I had some comments and questions 
on section 2.4

Section 2.4 describes several datatypes.  The syntax for these datatypes 
is described informally.

Q1.  Why not use BNF to describe the syntax?

The section includes algorithms for parsing the string representation.

Q2.  Why are these algorithms required?  Typically, it is hard to get 
the bugs out of them.
Larry say they are for conformance/consistency.  If so, why not just 
reference standard works such as
ISO 8601 or IEEE 754.

Q3.  Does HTML5 convert the string representation to binary for, say, 
floating point numbers?
If so, I'm sure, implementations just use the native language libraries 
such as the java Math library.
Why not just refer to these?

Note that XML Schema covers much of the same ground and may be a good 

All the best, Ashok
