SAC

SAC is the "Simple API for CSS."  SAC provides a standard interface for CSS parser and supposed to work with CSS1, CSS2, CSS3.  SAC was posted as a W3C Note in October 2000 and was produced as part of the work of the W3C Style Activity.

In addition to the W3C Note, software is available for download from the W3C.  One of the successes of the XML syntax was the interoperability between the XML parsers. This interoperability has been accomplished with the Simple API for XML ([SAX]). SAC plays a similar role for CSS.  The SAC download includes a parser interface that enables an application to parse a CSS style sheet, a CSS rule, a CSS selector and a CSS document handler.
