This sort of note would normally be included as a scope note, which can 
contain notes on other concepts which are included or excluded from the 
scope of the concept to which it applies. These notes are not generally 
designed to be understood by machines, so the syntax is not fixed. The 
example you quote could be shown as

restrictive business practices
SN: For restrictions on market entry USE market entry
RT: market entry

though the RT entry may be redundant. You could add, if desired, the 
additional entry as a non-preferred term:

restrictions on market entry
USE: market entry

and the (automatically-created) reciprocal entries:

market entry
UF: restrictions on market entry
RT: restrictive business practices

I don't think it is necessary to introduce another type of relationship; 
the ISO 25964 model allows for custom notes, but as this form of 
reference to another concept is very common in scope notes that seems 
the natural place to keep it.
