Headings/titles can be added by making use of either the "h" or the "header" tag. The "level" parameter controls the size/level of the heading, it must be a number between 1 and 6. The optional "class" parameter allows the use of a desired CSS class. The optional "anchor_name" parameter makes it possible to add an anchor to the heading. Usage:

<h [level=""] [class=""] [anchor_name=""] [custom_parameter="" [...] ]>Example</h>

or

<header [level=""] [class=""] [anchor_name=""] [custom_parameter="" [...] ]>Example</header>

The custom parameters are optional. Their names must be specified using the "CustomAttributes[]" array in the [header] block within an override for the "content.ini" configuration file. When used, a custom parameter will be available as a template variable with the same name as it was specified in the tag itself.

By default, the specified levels are increased by one. In other words, a level 1 header in the XML block will become a level 2 header (H2) in the resulting HTML. The reason for this is because the H1 tag is reserved for the name / main title of the content object. The headings inside the XML block will thus become subheadings of the main title. This behavior can be changed by creating an override template for the "/content/datatype/view/ezxmltags/header.tpl" template (it can not be controlled from within an configuration file).
