I'm sorry, but I must be missing something.  The allowed values for this 
property in the cited specification are a superset of the CSS 2.1 values (and in 
fact are a superset of the proposed CSS 3 Text values), and are NOT the same as 
the proposed SVG 1.2 values (which are a proper subset of the CSS 3 Text values 
and neither a subset nor a superset of the CSS2.1 values).  Could you please 
point out what, exactly, I'm missing?

I believe the concern of the CSS WG is that per SVG 1.2 a UA cannot parse the 
"text-align" CSS property without knowing whether it's being applied to an SVG 
element (since if it is, per the SVG 1.2 specification of the property the UA 
must throw out the declaration if "left" or "right" is the specified value). 
There is no reasonable way to do this in a mixed-namespace context where the 
same rule may be applied to both SVG and non-SVG elements.
