LeeAnnKorecky - 20 Nov 2002 Added "in" in front of "early." Changed "advent" to a small "a."
VivDunstan - 08 Dec 2002 Mentioned that parsers are included in authoring systems. Tweaked a few things elsewhere (recapitalised + italicised Advent; removed unneeded extra word + double quotes). Also rearranged the last few sentences so they read more easily.
