> Memoryleak:
> Inside CoreDocumentImpl a HashTable resides that holds an id string to element mapping.
> If an element is removed from the DOM this Map is only updated if one also removes the id attribute.
> Thus the element is not garbage collectable.
> Solution:
> Use an Map implementation that holds only a weak reference to it's values.
> See attached patch
