Consider the following component:

<#alert onclose="{iWasClosed()}">Foo</alert>

and

<#alert>Foo</alert>

where the close callback wasn't passed - currently there is no way (?) of distinguishing those 2 situations. It might be useful in cases like this one where we want to add (or not) a close button to the alert, depending if a callback was provided or not.

Can't we use the defaultValue attribute definition property for that ?
