[css3-values] attribute parsing with attr()

The section uses a bunch of "The attribute value will be interpreted as
X" but I think it should instead make sure the following questions are
answered without ambiguity:

1. Can CSS escape work in an attribute that's parsed as 'string',
'color', 'url', 'length', 'angle', 'time', 'frequency'?

2. Are CSS comments allowed for all types besides 'string' and 'url',
esp. for 'color', which accepts multiple tokens?

3. Are attr(), calc() and cycle() allowed as attribute value?

4. Are trailing spaces allowed?
