/*
 * Reference:RFC 6020.
 * The "type" statement takes as an argument a string that is the name
 *  of a YANG built-in type or a derived type, followed by an optional
 *  block of sub-statements that are used to put further restrictions
 *  on the type.
 *
 *  The restrictions that can be applied depend on the type being restricted.
 *  The type's sub-statements
 *
 * +------------------+---------+-------------+------------------------------------+
 * | substatement     | section | cardinality | mapped data type                   |
 * +------------------+---------+-------------+------------------------------------+
