I am sorry, but we cannot make our implementation available to the public 
at this time. We will probably be able to show it to W3C members sometime 
in the not too distant future, but subject to W3C confidentiality rules.

I can say, however, that Adobe does know how to read specifications, how to 
implement software that conforms to specifications, how to find existing 
public-domain test suites, how to develop our own test suites, and how to 
test against existing content on the Web. Adobe played a key role in the 
CSS2 specification process, particularly in the authoring process for the 
sections on the CSS2 box model. I will also say that Adobe has multiple 
products which support all of CSS, not only the "CSS inline model". Adobe 
GoLive is a product focused on HTML and CSS authoring. Adobe Acrobat 
includes a full CSS engine with the ability to parse arbitrary CSS-styled 
HTML on the Web and convert it to PDF. In fact, I find your comment about 
whether it is possible to "ascertain that this text engine is actually 
compatible with the CSS inline model" to be rather insulting.
