Detailed Description

SBMLNamespaces objects are used in libSBML to communicate SBML Level and Version data between constructors and other methods. The SBMLNamespaces object class holds triples consisting of SBML Level, Version, and the corresponding SBML XML namespace. Most constructors for SBML objects in libSBML take a SBMLNamespaces object as an argument, thereby allowing the constructor to produce the proper combination of attributes and other internal data structures for the given SBML Level and Version.

The plural name (SBMLNamespaces) is not a mistake, because in SBML Level 3, objects may have extensions added by Level 3 packages used by a given model and therefore may have multiple namespaces associated with them. In SBML Levels below Level 3, the SBMLNamespaces object only records one SBML Level/Version/namespace combination at a time. Most constructors for SBML objects in libSBML take a SBMLNamespaces object as an argument, thereby allowing the constructor to produce the proper combination of attributes and other internal data structures for the given SBML Level and Version.
