I assume you mean 'gr', as 'gd' only appears twice in the draft and  
without definition.

Please add to the table in section 3.3.2 Absolute length units:

   um   micrometers (µm); 1um is equal to 1/1000 millimeter.
   dd   didot; 1dd is equal to 3/8 millimeter.
   cc   cicero; 1cc is equal to 12 didots.
   q    kyu; 1q is equal to 1/4 millimeter.

Although not many a designer uses these (yet or still), they should  
be reasonably cheap to implement.

Please add, with much less emphasis, to section 3.3.3 Relative length  
units:

   ln   the line height of the element (or the parent element's line  
height if set on the ‘line-height’ property)
   pel  device pixel

Remove the phrase "are used with aural cascading style sheets" from  
3.3.7 Angles, 3.3.8 Times and 3.3.9 Frequencies, because those units  
may (and will) be used by other parts of CSS, e.g. Transitions and  
Animations. Let Modules limit the range or specify the clipping of  
units, like angles in aural CSS.

Do angles need minutes ('min') and seconds (maybe 'sec' in opposition  
to temporal 's'), do times need minutes more?

Change the MAY to a SHOULD requirement in 3.5.2 The ‘url’ function:

| The URI may be quoted with single quote (') or double quote (")  
characters.

The same should be done to font families.

| Parentheses, commas, whitespace characters, single quotes (') and  
double
| quotes (") appearing in a URI must be escaped with a backslash:

If I remember the RFCs correctly, of these only commas and perhaps  
parentheses may appear in URIs. (I'm not sure about fragment  
identifiers, though.)

Drop the first occurence of 'RGB' in 3.6.2 Colors, there's HSL and  
perhaps more in the future.
