Property 'dtype:order index'

The property "dtype:orderIndex" is an annotation property to specify a position that some value or structure will have. One use is to specify the place that a resource has in a sequence. One use is on property occurrences in class axioms. Here "vaem:orderIndex" is placed on a restriction to specify how that property may be transformed into a representation where ordering has some importance, for example, in XML Schema sequences.
