+/*
+ * 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 |
+ * +------------------+---------+-------------+------------------------------------+
+ * | bit | 9.7.4 | 0..n | - YangBit used in YangBits |
+ * | enum | 9.6.4 | 0..n | - YangEnum used in YangEnumeration |
+ * | length | 9.4.4 | 0..1 | - used for string |
+ * | path | 9.9.2 | 0..1 | - TODO leaf-ref |
+ * | pattern | 9.4.6 | 0..n | - used for string |
+ * | range | 9.2.4 | 0..1 | - used for integer data type |
+ * | require-instance | 9.13.2 | 0..1 | - TODO instance-identifier |
+ * | type | 7.4 | 0..n | - TODO union |
