 * morkMid: all possible ways needed to express an alias ID in Mork syntax
 */

/*| morkMid: an abstraction of all the variations we might need to support
**| in order to present an ID through the parser interface most cheaply and
**| with minimum transformation away from the original text format.
**|
**|| An ID can have one of four forms:
**| 1) idHex            (mMid_Oid.mOid_Id <- idHex)
**| 2) idHex:^scopeHex  (mMid_Oid.mOid_Id <- idHex, mOid_Scope <- scopeHex)
**| 3) idHex:scopeName  (mMid_Oid.mOid_Id <- idHex, mMid_Buf <- scopeName)
**| 4) columnName       (mMid_Buf <- columnName, for columns in cells only)
**|
**|| Typically, mMid_Oid.mOid_Id will hold a nonzero integer value for
**| an ID, but we might have an optional scope specified by either an integer
**| in hex format, or a string name.  (Note that while the first ID can be
**| scoped variably, any integer ID for a scope is assumed always located in
**| the same scope, so the second ID need not be disambiguated.)
**|
**|| The only time mMid_Oid.mOid_Id is ever zero is when mMid_Buf alone
**| is nonzero, to indicate an explicit string instead of an alias appeared.
**| This case happens to make the representation of columns in cells somewhat
**| easier to represent, since columns can just appear as a string name; and
**| this unifies those interfaces with row and table APIs expecting IDs.
**|
**|| So when the parser passes an instance of morkMid to a subclass, the
**| mMid_Oid.mOid_Id slot should usually be nonzero.  And the other two
**| slots, mMid_Oid.mOid_Scope and mMid_Buf, might both be zero, or at
**| most one of them will be nonzero to indicate an explicit scope; the
**| parser is responsible for ensuring at most one of these is nonzero.
