Out of Memory Error with SaxonEE 10.6

[margaretha]

There was an out of memory error during WikiXML to I5 conversion. The problem seems to come from net.sf.saxon.event.StreamWriterToReceiver. In Saxon 10.6 it has a namespace stack that contains huge amount of objects.
The StreamWriterToReceiver is used to write the final I5 file. It seems that the class always adds objects to the stack and never pop them.
