No and yes :-)

XML Schema allows mixed content, with full flexibility of the
configuration of elements allowed.  But the text allowed thereby is
not typed.

E.g. to reconstruct <!ELEMENT foo (bar|mum|#PCDATA)*> we would write

<xs:complexType mixed='true'>
 <xs:choice minOccurs="0" maxOccurs="unbounded">
  <xs:element name="bar"/>
  <xs:element name="mum"/>
 </xs:choice>
</xs:complexType>
