    Description

      Ability to easily create a meta tag (e.g. http://developer.apple.com/library/safari/#documentation/appleapplications/reference/safarihtmlref/articles/MetaTags.html or http://www.webmarketingnow.com/tips/meta-tags-uncovered.html ) via a new trh:meta tag.

      Currently it is quite tedious to create a meta tag out of a component:

      <tr:document ...>
      <f:facet name="metaContainer">
      <tr:group id="metaContainer">
      <tr:outputText escape="false"
      value='<meta name="viewport" content="width=device-width">'
      id="metaTag1"/>
      <tr:outputText escape="false"
      value='<meta name="apple-mobile-web-app-capable" content="yes">'
      id="metaTag2"/>
      <tr:outputText escape="false"
      value='<meta http-equiv="refresh" content="2;url=./test/index.jspx">'
      id="metaTag3"/>
      </tr:group>
      </f:facet>
      </tr:document>

      It would be much better if we had a trh:meta component that looked like this:

      <tr:document ...>
      <f:facet name="metaContainer">
      <tr:group id="metaContainer">
      <trh:meta name="viewport" content="width=device-width"/>
      <trh:meta name="apple-mobile-web-app-capable" content="yes"/>
      <trh:meta name="refresh" nameType="http-equiv" content="2;url=./test/index.jspx"/>
      </tr:group>
      </f:facet>
      </tr:document>

      So I would like to see a new trh:meta component that has an API like this:

      Tag name: <trh:meta>
      UIComponent class: org.apache.myfaces.trinidad.component.core.CoreMeta
      Component type: org.apache.myfaces.trinidad.CoreMeta
      The meta component generates an HTML meta tag and is intended to be used inside either the trh:head tag or the document component's metaContainer facet.

      Events
      Type Phases Description
      org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke Application, Apply Request Values Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.

      Attributes
      Name Type Supports EL? Description
      attributeChangeListener javax.el.MethodExpression Only EL a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.
      binding org.apache.myfaces.trinidad.component.core.CoreMeta Only EL an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.
      id String No the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:

      • Must not be a zero-length String.
      • First character must be an ASCII letter (A-Za-z) or an underscore ('_').
      • Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').

      rendered boolean Yes whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client).
      name String Yes the name or http-equiv attribute of the meta attribute (see nameType)
      nameType String Yes "name" or "http-equiv" indicating which kind of name attribute is desired ("name" is the most common attribute but some older meta tags need "http-equiv")
      content String Yes the content of the meta attribute
