// Tag schema. All tags that are used must be declared in the schema.
//
// Syntax:
// {a, b} = a set of tags
// a      = on the left-hand side of “->”, a set of one tag can omit the braces
//      ?{a, b} = must have one or none of these tags (one, optional)
//      1{a, b} = must have one and only one of these tags (one, required)
//      +{a, b} = must have one or more of these tags
//      !{a, b} = must not have any of these tags
// A=   This is a set being labelled with the single letter on the left-hand side
//      of “=”. It can then be substituted on the right-hand side for a set, using 
//      the same syntax, so +A would be one or more tags from that named set.
//
// ->   If ALL the tags are present on the left, then the rule holds on the right. If
//      no arrow is present in a rule, it holds for ALL tagged models.
//
// Comments, as you may have guessed, start with “//”
