Revised document conformance text

[MURATA Makoto (FAMILY Given)]

Chris,

I strongly think that we should keep WML/PML/SML strict conformance
classes.

First, we need the APPLICATION conformance calss "WML strict".
This is to allow implementations to support WML without supporting PML 
or SML.  (We can  start to reformulate application conformance 
classes, but that is going to be a long and difficult battle.)  Second, 
WML/PML/SML strict conformance clases appear in Part1 (PML strict in 
page 2793, SML strict in page 1742, and WML strict in page 198) and 
also in Part 4 (Page 1).

Cheers,
Makoto
