Main subject scheme identifier
An ONIX code which identifies a subject scheme which is designated for use in a <MainSubject> composite. Mandatory in each occurrence of the composite, and non-repeating.
When the scheme listed in the code list display is annotated “Code”, use the associated <SubjectCode> element to carry the value (if so required, the <SubjectHeadingText> element can be used simultaneously to carry the text equivalent of the code). When the scheme is annotated “Text”, use the <SubjectHeadingText> element to carry the text of the subject heading.
