-/// String Number for a Null terminated string, 00h stands for no string available.

+/// application software to deal with pointers embedded in the SMBIOS structure. Each string is terminated with a null
+/// (00h) BYTE and the set of strings is terminated with an additional null (00h) BYTE. When the formatted portion of
+/// a SMBIOS structure references a string, it does so by specifying a non-zero string number within the structure's
+/// string-set. For example, if a string field contains 02h, it references the second string following the formatted portion
+/// of the SMBIOS structure. If a string field references no string, a null (0) is placed in that string field. If the
+/// formatted portion of the structure contains string-reference fields and all the string fields are set to 0 (no string
+/// references), the formatted section of the structure is followed by two null (00h) BYTES.
