  We propose an XML-based standard for formulation of field theoretical models.
The goal of creation of such a standard is to provide a way for an unambiguous
exchange and cross-checking of results of computer calculations in high energy
physics. At the moment, the suggested standard implies that models under
consideration are of the SM or MSSM type (i.e., they are just SM or MSSM, their
submodels, smooth modifications or straightforward generalizations).
