SYSML21 — It is unclear how to obtain the data required for compartments

This section is for States which has the following specification:
states-compartment = line with 'states' label
states-compartment-contents
states-compartment-contents = (states-compartment-element)* '…'?
states-compartment-element =
el-prefix? OccurrencePrefix ActionUsageDeclaration

Regarding the processing of states-compartment-element, given the abstract item represented by a symbol, do I blindly follow all relationships in any direction to a StateUsage as appropriate in this case, and similarly for other examples?
This 'states-compartment' keyword is only referenced by the compartment keyword which seems to indicate that it is appropriate for any symbol. Is this assumption correct?
