module REXML
# A template for stream parser listeners.
# Note that the declarations (attlistdecl, elementdecl, etc) are trivially
# processed; REXML doesn't yet handle doctype entity declarations, so you
# have to parse them out yourself.
# === Missing methods from SAX2
# ignorable_whitespace
# === Methods extending SAX2
# +WARNING+
# These methods are certainly going to change, until DTDs are fully
# supported. Be aware of this.

# Handles a doctype declaration. Any attributes of the doctype which are
# not supplied will be nil. # EG, <!DOCTYPE me PUBLIC "foo" "bar">

# If a doctype includes an ATTLIST declaration, it will cause this
