/*This translator imports OpenURL ContextObjects encapsulated in XML
* documents, as described at:
* http://alcme.oclc.org/openurl/servlet/OAIHandler?verb=GetRecord&metadataPrefix=oai_dc&identifier=info:ofi/fmt:xml:xsd:ctx
* The schema for such XML documents is at:
* http://www.openurl.info/registry/docs/xsd/info:ofi/fmt:xml:xsd:ctx
*
* This format is used in several places online, including Brown University's FreeCite
* Citation parser (http://freecite.library.brown.edu/welcome) and Oslo University's
* X-Port (http://www.ub.uio.no/portal/gs.htm or http://x-port.uio.no/).
*
* The approach we will take is to convert this into COinS, so that we can
* piggy-back off of the perhaps more robust support in the core Zotero code.
