Portlet
> Overview
> The `portlet-entry` element is the main element encountered in the Registry. It describes a Portlet object that can be used within a portal page description. There are 3 main types of `portlet-entry` definitions, controlled by the value of the `type` attribute in the entry: abstract These portlets cannot be used directly in a portlet page and simply provide a configuration template for creating ref portlet-entry. The `classname` element is required in an abstract portlet instance These are the default portlet entries created within the registry and describe standard Java component complying to the Portlet API that can be added directly within a portal page. The `classname` element is required in an instance portlet ref These entries are the more frequently encountered definitions in the registry. They define portlets that reference another existing portlet entry in the registry, yet override or complement the previous definitions with additionnal parameters. The `parent` attribute is required in a ref portlet and must refer another existing abstract or instance portlet, but not another ref portlet. The `classname` element should not occur within a ref prtlet definition. In addition to the `type` attribute, portlet entries can also use standard attributes and elements that can be used in most other registry entries and are explained here

> Usage notes
> > ## Parameter handling Some parameters have special meanings when encountered in a `portlet-entry` defintion:
> > Name | Minimum Version | Usage
> > --- | --- | ---
> > _showtitlebar | 1.4b1 | Will cause the default portlet control not to draw any title bar around the portlet. This behavior is deprecated 1.4b2 and replaced by the more powerful `_control` attribute associated with a no title bar control like "ClearControl"
> > _control | 1.4b2 | Will cause any new instance of this `portlet-entry` to be associated with the control specified in the parameter value when added to a portal page.
> Also note that any parameter starting with a "_" will not be ignored by the default portlet customizer.
> Examples
> > The first example presents a minimal abstract type portlet definition. Note that it's defined as hidden to prevent the entry from showing up when browsing for portlets
> >     <portlet-entry name="Velocity" type="abstract" hidden="true">
> >       <classname>org.apache.jetspeed.portal.portlets.VelocityPortlet</classname>

Control
> Overview
> The `portlet-control-entry` element defines the available `PortletControl` available to decorate the different portlets. The `portlet-control-entry` definition is nearly identical to those of instance type `portlet-entry`, expect that there's no `category`, `url` or caching related attributes.

Media
> Overview
> The `media-type-entry` element defines the media types supported the portal instance. These media types are defined by a MIME content type, an optional character set and an optional set of user agent capabilities required to correctly access this media type. The media types are referenced by the `portlet-entry`, `portlet-control-entry` and `portlet-controller-entry` to define when these entries can be used.

Standard
> Overview
> > Several attributes and inner elements can be found in all registry entry types with similar semantics. This section describes these attributes and elements.
> > Name | Type | Description
> > --- | --- | ---
> > hidden | attribute | The `hidden` attribute that can be set on the registry entries and parameters to prevent them from being visible in a user browser. Usage of this attribute should considered deprecated since the same functionality can be achieved better by using the `security` elements.
> > meta-info | element | The `meta-info` element is used to describe properties of the registry entry. It can currently contains the 3 following sub-elements: title description image
> > security-ref | element | The `security-ref` element is used to describe access rights on the registry entry or parameter considered.
