Dijit _AttachMixin Test

This markup may have come from a server side templating engine like Catalyst. The aim is to allow us to use data-dojo-attach-* magic on the content.
Change the input value to see attach event and attach point at work.

This test shows an inner dijit being created with attachScope referencing its enclosing dijit.

This tests that nodes inside of data-dojo-attach-point="containerNode" are ignored
