Containing Schema: schema.xsd
Abstract
Documentation:
A structured identifier. Supports compund identifiers such as IChI. At present uses the V0.9 IChI XML representation verbatim but will almost certainly change with future IChIs. The inclusion of elements from other namespaces causes problems with validation. The content model is deliberately LAX but the actual elements in IChI will fail the validation as they are not declared in CML. For simple scalar values the value attribute can be used with empty content. Where an identifier has several components a series of label elements can be used. 2003-07-10: Fixed count on identifier children.. 2003-03-12: Added isotopic and atoms..
