Ok, these all look good to me.

Except, this error message change

-ERROR: property "ename" of element variable "src" not found
+ERROR: none of the property graph elements associated with variable
"src" have property with name "ename" defined

I don't know, that seems quite a complicated message for such a simple
mistake. Also, properties are associated with labels, not with graph
elements, so this seems misleading.
