SFL's Architecture Of Language Classified By SFL Relations

A. system networks
i. delicacy = elaboration + attributive
ii. disjunction = extension: alternative
iii. conjunction = extension: addition
iv. entry condition = enhancement: condition
v. realisation statement = elaboration + identifying

B. rank scale = extension: composition

C. realisation = elaboration + identifying
1. higher stratum realised by lower stratum [stratification]
2. system realised by structure [axis]
3. function realised by form [rank scale]

D. instantiation cline = elaboration + attributive
