  This class was auto-generated by the PythonClass plugin for PYANG
  from YANG module ietf-network - based on the path /networks/te/templates/link-template/te-link-attributes/label-restrictions/label-restriction/label-step. Each member element of
  the container is represented as a class variable - with a specific
  YANG type.

  YANG Description: The step increment between labels in the label range.
The label start/end values will have to be consistent
with the sign of label step.  For example,
'label-start' < 'label-end' enforces 'label-step' > 0
'label-start' > 'label-end' enforces 'label-step' < 0.
