equation — A displayed mathematical equation
equation ::= (blockinfo?, (title,titleabbrev?)?, (informalequation| (alt?, (graphic+|mediaobject+))))
An Equation is a formal mathematical equation (with an optional rather than required title).
If the MathML Module is used, Equation can also contain the mml:math element.
Formatted as a displayed block. For an inline equation, use InlineEquation.
Processing systems that number equations or build a table of equations at the beginning of a document may have difficulty correctly formatting documents that contain both Equations with Titles and Equations without Titles. You are advised to use InformalEquation for equations without titles.
These elements contain equation: answer, appendix, article, bibliodiv, bibliography, blockquote, callout, caution, chapter, constraintdef, glossary, glossdef, glossdiv, important, index, listitem, msgexplan, msgtext, note, para, partintro, preface, procedure, qandadiv, qandaset, question, refsect1, refsect2, refsect3, refsection, refsynopsisdiv, revdescription, sect1, sect2, sect3, sect4, sect5, section, setindex, sidebar, simplesect, step, tip, warning.
Label specifies an identifying string for presentation purposes.
Generally, an explicit Label attribute is used only if the processing system is incapable of generating the label automatically. If present, the Label is normative; it will used even if the processing system is capable of automatic labelling.
