Are you sure your comment for "DefaultPresentationType" is valid, c.f.
with "LzDataElementMixin#setAttr" where any non-string input produces
a debug-warning (maybe it should just perform implicit string-coercion

I think the implicit conversion in as3 is a bug. I think we really want
to warn when someone sets a non-string value into a dataset, because
that is how they will learn to update their application to operate
correctly. (The string warning was added once presentation types were
working.)
We _could_ make the default presentation type be 'string', but that
would not be backwards compatible.
The LzDataNode,LzDataElement classes/mixins are indented to provide a
DOM-like functionality. So I checked out what other DOM implementations
do in that case (so how they handle non-string input where strings are
expected).
In Firefox, the input is coerced to a string, for example this creates a
attribute-node with the node-name "hello":
document.createAttribute({toString:function(){return "hello"}})
Is this covered somewhere in the DOM-spec?
