[ttml1] Normative CSS2 reference erroneously changed to CSS2.1 in Second Edition

palemieux has just created a new issue for https://github.com/w3c/ttml1:

== Normative CSS2 reference erroneously changed to CSS2.1 in Second Edition ==
The reference to CSS2 in Second Edition changed from:

> Bert Bos et al., Cascading Style Sheets, Level 2, W3C Recommendation, 12 May 1998. (See http://www.w3.org/TR/1998/REC-CSS2-19980512/.)

to 

> Bert Bos et al., Cascading Style Sheets, Level 2 Revision 1, W3C Recommendation, 07 June 2011. (See http://www.w3.org/TR/2011/REC-CSS2-20110607/.)

Two issues:

- there were normative changes between the two CSS versions, e.g. "16.6.1 The 'white-space' processing model" introduced in CSS2.1
- Second Edition continues to reference XSL 1.1, which references CSS2

Proposed resolution:

- revert normative reference to CSS2
