Sorry about that, I forgot to convert the method's implementation
to XML 1.0.  Here is the method below in XML 1.0:

<defmethod>
 <not>
 <attributes>
  <execute_path> age <is><attributes>optional</attributes></is>
    <and> <attributes> <execute_path> birth <is> <attributes> optional
</attributes> </is> </execute_path>
          </attributes>
    </and>
  </execute_path>
 </attributes>
 </not>
 </defmethod>

ConciseXML equivalent:
<defmethod> <not age.<is optional/>.<and birth.<is optional/> /> </>

There is always an XML 1.0 representation for
ConciseXML.  Here is Water Type and Water
Contract in XML 1.0:

<defclass>
  <field key="person"/>
  <field key="name"> required string </field>
  <field key="age"> optional integer </field>
  <field key="birth"> optional datetime </field>
  <field key="_precond">
    <defmethod> <not age.<is optional/>.
                             <and birth.<is optional/> />
    </defmethod>
  </field>
</defclass>


Equivalent in ConciseXML:
<defclass person
   name=required=string
   age=optional=integer
   birth=optional=datetime
   _precond=<defmethod> <not age.<is optional/>.
                             <and birth.<is optional/> />
            </defmethod>
</defclass>

I don't know how well it translates into English, but in French we
have
a metaphor saying that this is throwing the baby away with the water
of
its bath...

There is no reason to switch to a different markup language just
because
one of the schema languages of XML is weak!
