----------------------------------

Let's make another try at this. There was a continued discussion on the mailing list on this topic and people see value in the concept. There was more support for a mixin that would target specific types of embedded components rather than ids of components that was deemed as too brittle.

> The EmbeddedMixin concept allows applying mixins on embedded components of an existing component.
> Usage scenario:
> A mixin can have embedded mixins defined with the new @EmbeddedMixin annotation.
> A motivational demo can be found here http://dragansah.com/demoapp/embeddedmixinexamples
> Usage example:
> <t:grid t:mixins="mixinForGrid" />
> public class MixinForGrid
> {
>         // apply the MixinForGridCell mixin to the rows.gridCell subcomponent of the grid
>         @EmbeddedMixin(componentId="rows.gridCell")
>         private MixinForGridCell mixinForGridcell;
>         // render phases on the grid
>         void beginRender()
>         {
>         }
> }
> public class MixinForGridCell
> {
>         // render phase on gridCell
>         void beginRender()
>         {
>         }
