No!

The content of an element is validated either against the parent type P or
against the subtype S. If it's validated against P then "extension" elements
are allowed; it it's validated against S then they aren't. Which type is
used for validation depends on the type defined in the element declaration
and/or the value of xsi:type on the instance.
