extends RequestContextAwareTag

Superclass for tags that output content that might get HTML-escaped.

Provides a "htmlEscape" property for explicitly specifying whether to apply HTML escaping. If not set, a page-level default (e.g. from the HtmlEscapeTag) or an application-wide default (the "defaultHtmlEscape" context-param in `web.xml`) is used.
