The spec [1] says: "The tmcl:regular-expression-constraint constrains all values of a given name or occurrence type shall match a given regular expression." This is also what the meta tmcl schema does when applied. So you can formulate constraints on name and occurrence values, but not variants. The reason for this is probably because variants are untyped, so there is no statement type which you can attach the constraint to.
