Identifies a subject or type of content that makes this element semantically special
This attribute can be used to name or describe a special function for an associated element, for example, to record that the content of a table cell is a total or subtotal amount, that a side bar (element <boxed-text>) contains a case study, or that a <statement> element’s content is a theorem. In converting from other tag sets into the tagset described by this DTD. This attribute can be used to preserve semantic meanings that can’t be captured by this tag set. For example, the DTD has no <generic-drug-name> element, but the sense of such an element can be preserved by tagging the content as a <named-content> element with a content-type attribute value of “generic-drug-name”.
This attribute could identify a drug name, company name, or product name. It could also be used to define systematics terms, such as genus, family, order, or suborder. Similarly, it could be used to identify biological components, such as gene, protein, or peptide. Therefore, the values may include information classes, semantic categories, or types of nouns such as “generic-drug-name”, “genus-species”, “gene”, “peptide”, “product”, etc.
The presence of a content-type attribute may be used to treat its element in a special way, for example, giving the work, phrase, or structure a different look in print or on display. This type of formatting may be guided by the value of the attribute, for example, making all circulatory system words (identified by a <named-content> element) red or putting a background image behind case studies.
|Text, numbers, or special characters||Names/describes the special function for the <named-content> that cannot otherwise be described by the elements in this DTD Suite. For example, a medical article might use the value “body-system” or “gene” while a management article might use the value “product-name” or “stock-code”.|
|Restriction: This attribute must be specified if the element is used.|
|Text, numbers, or special characters||Names/describes any special semantics of the associated element. This may be used to preserve the semantic intent of prior tagging, for example, to record that a table cell was a total or subtotal amount. This may also be used to attach information classes to an element for retrieval purposes.|
