Hi All, I have just noticed that the schema at: http://rs.tdwg.org/tapir/1.0/schema/tapir.xsd isn't valid according to Oxygen 8.0. E cos-all-limited.1.2: An 'all' model group must appear in a particle with '{'min occurs'}' = '{'max occurs'}' = 1, and that particle must be part of a pair which constitutes the '{'content type'}' of a complex type definition. Am I missing something - I appreciate that there are a stack of emails I need to work back through. All the best, Roger ____________________________________________________________ Roger Hyam <roger@tdwg.org> ____________________________________________________________ Biodiversity Information Standards: http://www.tdwg.org/ "Working To Make Biodiversity Data Global" ____________________________________________________________ TDWG Standards Architecture: http://wiki.tdwg.org/twiki/bin/view/TAG LSID RDF Vocabularies: http://wiki.tdwg.org/twiki/bin/view/TAG/ LsidVocs ____________________________________________________________
