Model Description

Text, numbers, or special characters

This element may be contained in:

<array>, <chem-struct>, <chem-struct-wrap>, <disp-formula>, <disp-formula-group>, <fig>, <fig-group>, <graphic>, <inline-graphic>, <inline-supplementary-material>, <media>, <preformat>, <supplementary-material>, <table-wrap>, <table-wrap-group>


In the following example, the <alternatives> element is used to wrap a mathematical expression encoded in MathML with a graphic image of the same expression for use in environments where MathML is not supported.
