Description (partial)

The 'match vlan' statement only allow either one VLAN ID, or a range of continuous VLAN IDs:
7600-1(config-cmap)#class-map match-any dummy
7600-1(config-cmap)#match vlan ?
  <1-4095>  VLAN id
  inner     Inner tag to match

The ES+ module allows only 8 match statements per class-map, allowing multiple disjoint VLAN IDs within one 'match vlan' statement (separating the VLAN ID by comma like the 'switchport trunk allowed vlan' or the 'vlan' commands) would ease QoS policy configuration in which more than 8 disjoints VLAN IDs/ranges are required.

Class-map configuration.
