<!--Version 2.6 june 4, 2007  by Dmitry Ikan (Sage Change)
- added element art_subject to art_info to support the grouping of articles in a one level hierarchy on the HighWire TOC view pages.
- added attribute leader_text to elements grp_aut and grp_edt to capture and display leading text such as "On the behalf of" outside of the associated element.
- added ability to support more then one abstract to enable additional abstracts in foreign languages; by practice, the first abstract (no lang attribute) will always be English
- added attribute "lang" to element abstract with fixed values to support current HighWire supported languages: (German(de), Spanish(es), Franch(fr), Italian(it), Portuguese(pt))
- added attribute "sort" to the publication month <mm> tag to enable the association of a cross-year publication month (12-01) with the publication year. The allowed values are "first" and "last". First
assocates the first month (12 in the given example) with the publication year and last associates the second month (01 in this case) with the publication year. This enables proper sorting of the
publication month on the HighWire archive page.-->
