+            Tlv hex bytes consists of type filed (one byte), length field (one byte) and value/data of variable lengths. Length in unit of bytes, is given in one byte length field. 
+            Therefore the value can be maximum 255 bytes length.
+            The string MUST contains sequence of valid hex bytes. In the imported byte stream, one byte is represented as string of 2 characters, for example 2 character string (0x)AB 
+            represents value of a single byte. So the maximum length of this attribute is 512 (256 * 2 hex characters per byte) plus two, i.e 514.
