A word or phrase whose content/subject matter has special semantics or content-related significance. In print or display, such content is likely to be treated differently, for example, given a special typographic style such as italics or background shading.
The content-type attribute can be used to identify the subject or type of content that makes this word or phrase semantically special, and therefore to be treated differently. For example, this attribute could be used to identify a drug name, company name, or product name. It could be used to define systematics terms, such as genus, family, order, or suborder. It could also be used to identify biological components, such as gene, protein, or peptide. It could be used to name body systems, such as circulatory or skeletal. Therefore, values may include information classes, semantic categories, or types of nouns such as “generic-drug-name”, “genus-species”, “gene”, “peptide”, “product”, etc.
