Delete the attribute named <code>name</code>.  If the attribute has a
vector value, delete the <code>i</code>'th element of the vector.

@param clearname The name of the attribute to delete.  This can be an
attribute of any type, including containers.
@param i    If the named attribute is a vector, and <code>i</code> is
non-negative, the <code>i</code>'th entry in the vector is deleted.
If <code>i</code> equals -1, the entire attribute is deleted.
