-- Boundary-Scan Description Language (BSDL Version 0.0) is a de-facto
-- standard means of describing essential features of ANSI/IEEE 1149.1-1990 
-- compliant devices.  This language is under consideration by the IEEE for 
-- formal inclusion within a supplement to the 1149.1-1990 standard.  The
-- generation of the supplement entails an extensive IEEE review and a formal 
-- acceptance balloting procedure which may change the resultant form of the 
-- language.  Be aware that this process may extend well into 1993, and at
-- this time the IEEE does not endorse or hold an opinion on the language.
