I summarize for you the solutions proposed:

One solution is to wrap the element that can change inside another:

  <xsd:all>
   <xsd:element minOccurs="0" maxOccurs="1" ref="sending" />
   <xsd:element minOccurs="0" maxOccurs="1" ref="logging"/>
   <xsd:element minOccurs="0" maxOccurs="1" ref ="usetype"/>
  </xsd:all>

 <xsd:element name="usetype">
  <xsd:complexType>
   <xsd:choice>
    <xsd:element ref="useonly"/>
    <xsd:element ref="notuseonly"/>
   </xsd:choice>
  </xsd:complexType>
 </xsd:element>

The other one is to use a substitution group:

  <xsd:all>
   <xsd:element ref="sending"/>
   <xsd:element ref="logging"/>
   <xsd:element ref="usetype"/>
  </xsd:all>
 </xsd:complexType>
 <xsd:element name="usetype" abstract="true"/>
 <xsd:element name="useonly" substitutionGroup="usetype"> ... </xsd:element>
 <xsd:element name="notuseonly" substitutionGroup="usetype"> ... </xsd:element>
