* OleHandler provides implementations for the XSLT extension functions used by the WordML 2003 XSLT filters.
*
* The extension functions takes base64 encoded string representations of embedded OLE objects provided by the XML filter framework,
* stores them into a com.sun.star.embed.OLESimpleStorage and retrieves them later as individual base64 OLE objects.
*
* The implementation is ported from the former Java based implementation XSLTOleExtrater (sic)
*
* I believe the whole thing should provide round-trip editing of embedded OLE objects.
* I'm not sure if it currently does anything meaningful, because the Java implementation seems to be broken both in OOo and LibO.
