Can't parse the ietf-lisp-address-types.yang model

In the 'ietf-lisp-address-types.yang' yang model
each CASE in lisp-address/address CHOICE has wrong path specified for WHEN condition.

example:
<input>
<eid>
<address-type>...<address-type/>
<no-address/>
</eid>
</input>

(line 249)
leaf no-address {
when "../../address-type = 'laddr:no-addr-afi'"
should be
when "../address-type = 'laddr:no-addr-afi'"
