Detailed Description

fbc SBMLNamespaces extension for the “fbc” package.

This class of objects is defined by libSBML only and has no direct equivalent in terms of SBML components. This class is not prescribed by the SBML specifications, although it is used to implement features defined in SBML.

There are currently two possible namespaces defined for the Flux Balance Constraints package: "http://www.sbml.org/sbml/level3/version1/fbc/version1" and "http://www.sbml.org/sbml/level3/version1/fbc/version2". Despite both referencing SBML Level 3 Version 1 explicitly, both versions of this package (and all such packages) can be used without change in SBML Level 3 Version 2 documents. The only caveat is that features of the SBML Level 3 Version 2 specification that were not present in Level 1 may not be used by constructs from the Flux Balance Constraints package.
