Angle values for azimuth and elevation

-----BEGIN PGP SIGNED MESSAGE-----

Next up on my ACSS hit list is angle values for azimuth and elevation.  
The azimuth property specifies that an angle value be given in the range -
360deg <= x < 360deg.  First off, I don't see why -360deg should be 
included since it's equivalent to 0deg.  But more importantly, it's 
unclear to me whether other values, such as 370deg or 3.14rad (hmm, we 
need a way to say pi), are invalid, or if the UA should simply convert to 
the equivalent degree value in the range -360deg to 360deg.  (A UA 
conversion seems appropriate to me, FWIW.)

Similarly, the elevation property specifies an angle value in the range -
90deg to 90deg.  Does this mean that 270deg is invalid?  Shouldn't this 
angle value be normalized to the range -90deg to 90deg, contrary to what 
is stated in the definition of the angle unit?

Also...  In the definition of angle units, the draft states that "10deg 
and 350 deg are equivalent"  Shouldn't this read "10deg and 370deg are 
equivalent" since 10deg is co-related to 370deg, and since there is no 
whitespace permitted between the number and unit identifier?

And one final side note...  Would it be possible to include named anchors 
for each property in drafts like WD-acss and WD-print?  This allows me to 
provide direct links from property names in CSSCheck to the property spec, 
and would also facilitate a helpful table of contents in the WDs 
themselves.
