Render the markup for a <head> element.
Decode Behavior
No action is required during decode for this renderer.
Encode Behavior
Render the starting <head> element tag. Any attributes declared on the element must be passed through unmodified to the rendered output. At some point before rendering the closing </head> element tag, render any resources that have been targeted for this "head" element:
UIViewRoot instance.List of component resources targeted for this "head" element with a call to UIViewRoot.getComponentResources() with the String "head" as the argument.List of UIComponent instances and call encodeAll on each UIComponent instance. Any attributes declared on the element must be passed through unmodified to the rendered output.
Note that due to the cascading nature of CSS files, the order in which these files have been added to the view must be preserved when rendering the references to the files within the <head> element. Also, the end result of the rendered <head> section must be that any CSS files referenced due to previous calls to addComponentResource() do not adversely interfere with any CSS files manually placed in this section by the page author.
Render the ending </head> element tag.
