Entity Substitution Files
The following entity substitution files are located in the Arbortext-path\composer directory. Each file controls a different aspect of entity substitution, and uses the same XML format for specifying substitutions.
* 
Some of these files are purposefully void of mapping entries. These files exist as starting points for customization.
htmlEntSub.xml — Controls entity substitution for HTML (not XHTML) outputs.
* 
This file does not control entity substitution for the HTML Help content pane. Currently, there is no support for entity substitution for the HTML Help content pane.
htmlHelpNavEntSub.xml — Controls entity substitution for the HTML Help navigation pane.
xmlEntSub.xml — Controls entity substitution for XML outputs (includes XHTML).
textEntSub.xml — Controls entity substitution for XSL stylesheets that include a text output method.
For entity substitution when publishing using File > Publish > For Web, use the XSLT 2.0 character map feature describe at www.w3.org/TR/xslt20/#character-maps.
