/* $Id: xml_l.ll 2832 2007-12-01 01:05:01Z flaterco $
xml_l.ll Flex file for limited XML parser (just tags, no text).
This is *NOT* a general-purpose XML parser.
All things beginning with <! are treated as comments which are
terminated by the next > character. This means that you can't do
the following (shown in the XML FAQ):
<!DOCTYPE foo [
<!ENTITY alephhb cdata "à">
]>
However, it should be possible to add a simple DOCTYPE declaration
at such a time that I have a DTD:
<!DOCTYPE xtide SYSTEM "xtide.dtd">
