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.

Methods extending SAX2
WARNING
These methods are certainly going to change, until DTDs are fully supported. Be aware of this.

def attlistdecl(element, pairs, contents)
end
If a doctype includes an ATTLIST declaration, it will cause this method to be called. The content is the declaration itself, unparsed. EG, <!ATTLIST el attr CDATA REQUIRED> will come to this method as “el attr CDATA REQUIRED”. This is the same for all of the .*decl methods.

EG, “PUBLIC” @p long_name the supplied long name, or nil. EG, “foo” @p uri the uri of the doctype, or nil. EG, “bar”
