Purpose: { To personally study the practicallity of Rebol
being used as bridge between browsers and markup languages. } 
Comment: { The purpose for this script is to parse xml, xhtml, css, and
html and have it viewable/scriptable in its own  document window. 
This script has been taken from a larger portion that's used in a Rebol browser. 
This script is only prelimanary dialect, there will be lots of changes seeing that 
some of it does not work properly at this time.  If you would like to share 
code to improve the ml parser, email it to the ML (mailing list) so others can learn 
about it too.  Thanks }
