[higgins-dev] New version of higgins.owl (v1.15)

["Paul Trevithick" <paul@xxxxxxxxxxxxxxxxx>]

Please note: breaking change 1) below means that ALL files that import
higgins.owl will have to be tweaked (to add the ".owl" extension) to
owl:import statements and xmlns statements about higgins. 

Breaking changes:

1) Changed the xmlns:higgins and xml:base from:
  http://www.eclipse.org/higgins/ontologies/2006/higgins 
to:
  http://www.eclipse.org/higgins/ontologies/2006/higgins.owl

2) Removed all of the redundant *SimpleAttribute" strings from the names of
all SimpleAttribute subclasses and from the names of all simpleValue
sub-properties. 

3) Renamed subjectCUID to subjectId

4) Renamed ContextID to contextId

Nonbreaking changes (i.e. additions):

1) Copied in the
http://protege.stanford.edu/plugins/owl/owl-library/2005/08/07/xsp.owl
approach to modeling XSD datatypes 

Have updated the doc here too:
