doc_fast_attribute_removed Class Reference

Detailed Description

In SBML Level 3 Version 2, the "fast" attribute was removed. All reactions are assumed to be equivalent to reactions in previous levels/versions that have a "fast" attribute value of false. Users should be aware that even for previous levels/versions of the specification, "fast" attribute values of true never achieved widespread support, and many software packages may ignore it. To achieve the same or similar effects as setting the fast attribute to true for a given reaction, the KineticLaw attribute should be constructed to produce a value in the desired time scale, or else the reaction could be replaced with an AssignmentRule or AlgebraicRule.
