LDEV-1352: The XML output had namespace entries (wrong ones) scattered throughout the output, so now nearly all properties have their correct namespace nominated. This isn't obvious when you use Firefox to view the XML - you need to look at the text file directly.
LDEV-1352: Added properties and the IMSLD conditions that use the properties, to selectively hide/show the branches. Updated the LAMS schema file and removed some activity attributes that don't need to be in the export.
