Erik van Oosten commented on WICKET-2332:
-----------------------------------------

Hmm, perhaps org.apache.wicket.markup.Markup.makeImmutable() should be made 
public as well.

> Open up Markup ctor and MarkupContainer#renderNext

> Hi,
> I am writing a Swing like layout manager (with MIG layout manager's API 
> as inspiration). The layout manager will generate HTML, but also has the 
> ability to override this with HTML defined by the user. I have a 
> prototype that does this. It takes elements from the current 
> Markupstream, adds the elements that are missing, and then some more to 
> facilitate the layouting (well the last step is next on my todo list). 
> These elements are then put in a new markupstream that is used to drive 
> onComponentTagBody of the layout component.
> For this to work I had to open up 2 things:
> - org.apache.wicket.markup.Markup#Markup(): from default to public
>   I could have written my own implementation of IMarkup, but that seems 
> a bit overkill as I need exactly what is in Markup.
> - org.apache.wicket.MarkupContainer#renderNext(MarkupStream): from 
> private to protected (don't care if it stays final)
>   My onComponentTagBody implementation is loosely based on method 
> org.apache.wicket.MarkupContainer#renderAssociatedMarkup(String,String). 
> One of the methods I need to call to render children seems to be renderNext.
> Could these two be opened up?
