hex-list

Pattern: 
'(([0-9a-fA-F]){2}(:([0-9a-fA-F]){2})*)?' 

DEPRECATED: Use yang:hex-string instead. There are no plans to remove tailf:hex-list. A list of colon-separated hexa-decimal octets, for example '4F:4C:41:71'.

The statement tailf:value-length can be used to restrict the number of octets. Using the 'length' restriction limits the number of characters in the lexical representation
