Configuring the servlet filter
The startTemplate, markContent, and endTemplate tags will only render their output if they detect the presence of the Web Editor servlet filter. The tags can remain in the JSP page in production and have no effect until the servlet filter configuration is added to the web.xml file.
Configuring Web Editor forms
The Web Editor (AWE) uses a form to edit the node referenced by a markContent tag. By default, the form displayed will contain the cm:title, cm:description, and cm:content fields. An alternative form can be used by providing the markContent tag with a formId attribute.
