# This file implements a parser for html snippets, meant to be used by a
-# WYSIWYG editor. Hence it does not attempt to parse doctypes, <html>, <head>
-# or <body> tags, nor does it produce the top level "document" node in the dom
-# tree, nor nodes for html, head or body. Comments containing "fixfull"
-# indicate places where additional code is needed for full HTML document
-# parsing.
+# WYSIWYG editor.
+
+# The implementation is a pretty direct implementation of the parsing algorithm
+# described here:
+# http://www.w3.org/TR/html5/syntax.html#preprocessing-the-input-stream
+#
+# Deviations from that spec:
+#
+# Purposeful: search this file for "WTAG"
#
-# Instead, the data structure produced by this parser is an array of Nodes.
+# Not finished yet: search this file for "fixfull", "TODO" and "FIXME"
