YangTools can not parse VPP model

The problem is at line 398 with this description node:
description
/* DAW-NOTE-ORCH: subif classification attributes can only be set

• when the subinterface is created. Thus in order
• to modify them, the subif must be deleted then
• re-created with the desired classification values.
  */
  "VPP-CLI-COMMAND: create subif
  VPE-API MSG: create_subif
  PRIORITY: P1";

Here is the exception:
