To clarify a bit my position on CSS profiles and why I consider that  
a profile is NOT an umbrella specification.

How do you answer these questions?
     - What is CSS 3?
     - Why CSS 3 is useful to me?
     - Where can I use CSS 3?
     - What are the requirements to develop a CSS 3 authoring tools?  
browsers? library?

For example, I read in the Web community sometimes, people waiting  
for one of the feature of CSS 3 in their browsers, but there's no CSS  
3 profile for browsers.

I wonder how a developer will know about the list of profiles  
available for products.
I wonder how an author will know how to choose CSS 3 properties for  
his/her pages except by reverse deduction of what has been  
implemented in some browsers or a large number of browsers.

In the current page you gave, it is said

CSS level 3 is under development. It includes all of level 2 and  
extends it with new selectors, fancy borders and backgrounds,  
vertical text, user interaction, speech and much more.

:) not very informative.

I go to under development which goes to CSS: under construction

There's a link in this page to

The members of the CSS&FP Working Group have decided to modularize  
the CSS specification. This modularization will help to clarify the  
relationships between the different parts of the specification, and  
reduce the size of the complete document. It will also allow us to  
build specific tests on a per module basis and will help implementors  
in deciding which portions of CSS to support. Furthermore, the  
modular nature of the specification will make it possible for  
individual modules to be updated as needed, thus allowing for a more  
flexible and timely evolution of the specification as a whole.
This document lists all the modules to be contained in the future  
CSS3 specification.

Hmm not quite an introduction but more a roadmap.

Too bad because it could have been an Umbrella specification giving  
the relationships, the constraints, and a real introduction to the
