xmerl: Look up unknown prefixes in xmlContext when matching attributes
The core use case is a query where the original prefix in the scanned document is unknown (or varying). For example: xmerl_xpath:scan("//@ns:name", Doc, [{namespace, [{"ns", Uri}]}]) Previously, this would only return a result if the namespace prefix was an exact match.
