x:Static is not supported

x:Type doesn't seem to be either? What else is missing? I can submit a PR for these I think.

TypeExtension is implemented in Perspex, but OmniXAML could also include the very same implementation.

I have some doubts, though: why are they x:Type and x:Static instead of just Type and Static? The x prefix is always used for directives. In fact, the x prefix and its associated namespace is "virtual": it doesn't exist.

In my opinion, extensions shouldn't be under x: to provide a feeling of homogeneity.

Ok, I think probably the only reason to put them in the x: namespace is that people coming from other platforms will expect them to be there. I can live with just using {Type} and {Static} for now.

What about {x:Null}?

It would also be nice to have these builtins:
