UAF11 — Problem with EnhancedSecurityControl inheritance

Enhance is set to subtype DeriveReqt and goes between SecurityControl and EnhancedSecurityControl. This is not allowed in SysML as DeriveReqt is constrained to go between Requirements only (i.e. Classes), but EnhancedSecurityControl extends Activity. Even if the whole extension/inheritance are/aren’t inherited by sub Stereotypes, it doesn’t make sense that EnhancedSecurityControl has a different metatype. I think EnchancedSecurityControl was just not updated when SecurityControl was (i.e. it was left as it was in Beta 1).

Security Control and Enhanced Security Control are both specific SysML Requirements

Security Control and Enhanced Security Control are both specific SysML Requirements. It means Enhances relationship can inherit from DeriveReqt and can connect both.
