<chem-struct>

Chemical Structure (Display)

Chemical expression, reaction, equation, etc. that is set apart within the text.

Remarks

This element accommodates chemical reactions expressed in many ways: as text with emphasis tags, subscripts, and superscripts; as a preformatted area (<preformat>); as an included graphic; etc. The linking attributes may also be used to point to an external source such as a URI.
Display/Formatting Note: A chemical structure is assumed to be anchored at its position within the text.

Related Elements

The expression of a chemical reaction or other chemical structure goes inside the <chem-struct> element. The related element <chem-struct-wrap> is an outer wrapper that may hold, for example, both a chemical reaction and its caption or three related chemical expressions.
