@Deprecated
public abstract class RenderTagSupport
extends RenderTag

Support for all tags which render (an attribute, a template, or definition).

Properly invokes the defined preparer and invokes the abstract render method upon completion.

This tag takes special care to ensure that the attribute context is reset to it's original state after the execution of the tag is complete. This ensures that all all included attributes in subsequent tiles are scoped properly and do not bleed outside their intended scope.
