ISO-Specific Name For a Standards Development Organization
This element is specific to ISO-related standards processing and may be used only inside <doc-ident> within <iso-meta>, <reg-meta>, or <nat-meta>. The element is retained for backwards-compatibility purposes.
ISO Note: When used for ISO-related processing, the <sdo> element (which appears as a child of the <doc-ident> element) will usually have the same content as the <originator> element (which appears as a child of <std-ident>).
Also within ISO standards documents, the textual sub-components of <sdo> are closely related to the fields of ISO URNs as documented in RFC 5141 (from which some of the text describing them is borrowed). Content of this element is expected, though not required, to be:
(International Organization for Standardization)
(International Electro-Technical Commission)
(ISO/IEC joint work)
(ISO/CIE joint work)
(ISO/ASTM joint work)
(ISO/IEEE joint work)
Text, numbers, or special characters, zero or more
