++ Description: \spadtype{OpenMathErrorKind} represents different kinds
++ of OpenMath errors: specifically parse errors, unknown CD or symbol
++ errors, and read errors.
OpenMathErrorKind() : SetCategory with
coerce : Symbol -> %
++ coerce(u) creates an OpenMath error object of an appropriate type if
++ \axiom{u} is one of \axiom{OMParseError}, \axiom{OMReadError},
++ \axiom{OMUnknownCD} or \axiom{OMUnknownSymbol}, otherwise it
++ raises a runtime error.
OMParseError? : % -> Boolean
++ OMParseError?(u) tests whether u is an OpenMath parsing error.
OMUnknownCD? : % -> Boolean
++ OMUnknownCD?(u) tests whether u is an OpenMath unknown CD error.
OMUnknownSymbol? : % -> Boolean
++ OMUnknownSymbol?(u) tests whether u is an OpenMath unknown symbol error.
OMReadError? : % -> Boolean
++ OMReadError?(u) tests whether u is an OpenMath read error.
