My own 'covariate structure' (Lemke 1985), which includes Halliday's univariate type, is for the case of homogeneous relations of co-classed units, and should perhaps be called a 'structuring principle' rather than a kind of structure.

The Distinction Between Generality, Abstraction And Instantiation In SFL

Halliday & Matthiessen (1999: 615):

• generality (delicacy), of 
• abstraction (realisation), or of 
• token to type (instantiation);

1. Generality/delicacy is equivalent to hyponymy and can be construed as either an identifying or attributive relation;
2. Abstraction/realisation can only be construed as an identifying relation;
3. Instantiation can only be construed as an attributive relation.
