<chem-struct>

Chemical Structure (Display)

Definition

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

Remarks

Authoring Note: The model for this element will allow a chemical reaction to be expressed as: just text with emphasis tags, a MathML or TeX equation, a graphic, etc. Alternatively, if the reaction cannot be expressed in a simple fashion, the linking attributes may be used to point to an external source, such as a URI, for a more complete explanation.

Display Note: A chemical structure is assumed to be anchored at its position within the text.

Authoring Note: Accessibility elements (such as <long-desc>) should not be used with this element if they can be used as part of the containing Chemical Structure Wrapper <chem-struct-wrapper> element. Accessibility elements are allowed within this element only to handle the case in which a single <chem-struct-wrapper> wrapper element contains more than one Chemical Structure (Display) <chem-struct> within it.

Design Note: The decision was made not to add CML or other formal chemical markup language to this version of the DTD. Some equations can be marked up in MathML; others are just ASCII expressions with subscripts, superscripts, and special characters. The list class elements can be used to express the Elsevier DTD <compound-info> element.

Display 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 Chemical Structure (Display) element. The related element Chemical Structure Wrapper is an outer wrapper that may hold, for example, both a chemical reaction and its caption or three related chemical expressions.

Implementor’s Note: If CML is added, it will go within the related element <chem-struct>.
