conveys a list of one or more attributes related to an entitlement. An entitlement may contain an EntitlementType, which states what can be done at a gross level, e.g. that a party can make markets. It may be limited further within EntitlementGrp, e.g. that such market making is allowed only for a list of stocks. The EntitlementAttribGrp contains fine details clarifying or limiting the EntitlementType, e.g. that such market making must be conducted with a specific minimum quote size and a specific maximum spread.
