Individual component of a multi-part subject (for example, subject term, code for the term).
Subjects are used, typically, in searching and discovery or to provide headings for groups of articles in a printed or online generated Table of Contents. This element can name one of the components of a subjects, when that subject is a multi-part subject rather than a simple subject.
Best Practice: The @content type attribute should be used to indicate the type of part, for example, “ text ”, “ code ”, “ sponsor ”, etc.
<!ELEMENT compound-subject-part (#PCDATA %compound-subject-part-elements;)* >
(#PCDATA | bold | italic | monospace | overline | roman | sans-serif | sc | strike | underline | alternatives | inline-graphic | private-char | chem-struct | inline-formula | named-content | styled-content | sub | sup)*
Any combination of:
Coded subjects:
... <article-categories> <subj-group> <compound-subject> <compound-subject-part content-type="code">A1</compound-subject-part> <compound-subject-part content-type="text">Cellular and Molecular Biology </compound-subject-part> </compound-subject> <subj-group> <compound-subject> <compound-subject-part content-type="code">A11</compound-subject-part> <compound-subject-part content-type="text">Blood–brain barrier</compound-subject-part> </compound-subject> <subj-group> <compound-subject> <compound-subject-part content-type="code">A115</compound-subject-part> <compound-subject-part content-type="text">Permiability </compound-subject-part> </compound-subject> </subj-group> </subj-group> </subj-group> <subj-group> <compound-subject> <compound-subject-part content-type="code">A2</compound-subject-part> <compound-subject-part content-type="text">">Neurobiology </compound-subject-part> </compound-subject> </subj-group> </article-categories> ...
Using the type attribute to name the source and components:
... <article-categories> <subj-group subj-group-type="flesch-subject-headings"> <compound-subject> <compound-subject-part content-type="flesch-code2">A2</compound-subject-part> <compound-subject-part content-type="flesch-short-form">Neurobiology </compound-subject-part> </compound-subject> </subj-group> </article-categories> ...
