!-----------------------------------------------------------------------
! NOTE: These patterns WILL ONLY work with NEdit versions 5.1 and latter
!-----------------------------------------------------------------------
!
! To load:
!    1. Save this to a file
!    2. Start NEdit using the -import command line option
!        ex:      nedit -import <name of this file>
!	 that is: nedit -import ltm.pats
!    3. To retain the patterns in your NEdit startup file...
!          Preferences -> Save Default... and click "OK".
!
! Abstract:
!    These patterns attempt to highlight text written in
!    Linear Topic Map Notation (LTM).
!    LTM notation records topic maps.
!    The formal syntax is defined in Lars Marius Garshol's
!    'Definition and introduction' at 
!		http://www.ontopia.com/download/ltm.html. 
!    (Topic Maps have an extensive literature: formal 
!    documents include ISO 13250 and the specification for
!    XTM 1.0 at http://www.topicmaps.org/xtm/1.0/ )
!
! Features:
!    o  This is a very simple creation by a novice: Comments
!	are italicised. Topics definitions are in black, association
!	definitions in red, and occurrence definitions in blue.
!	There is some minimal further highlighting within definitions.
!	Directives are in bold red.
!
! Limitations:
!    o  Probably many: see 'Features'.
!    o  Extensive checking has not yet been done, especially against
!	texts created by several authors (LTM is very liberal about 
!	the use of whitespace, and not all possibilities may have been
!	covered).
!    o  These patterns could be made slightly more complicated to
!	allow for some basic syntax checking (for example at present
!	there is a check that Occurrence definitions consist of
!	three sections separated by two commas and that the third section
!	looks roughly like a Specification or a Description). Doing this
!	for Topic and Association definitions would need to countenance 
!	many possible 'or's' in the syntax ...
!    o	Scoping is not highlighted (but because of that does show up 
!	nicely ;-)>
