Food for thoughts:

Add a bindings concept to XML schema to handle boolean ,
enumeration data types and language issues.

An binding is a sequence of pairs of value space expression and lexical
representation
where each value space expression must express a subspace (or equal) of
the
data types value space. The order of the pairs is important since it
defines a confliction
resolution order.


Examples:
<datatype name=?boolean?>
  <basetype name=?integer?/>
    <minInclusive>0</minInclusive>
    <maxInclusive>1</maxInclusive>
</datatype>

<datatype name=?myBoolean?>
    <basetype name=?boolean?/>
   <binding>
     <bind><value> 1 <value>  <pattern> [Tt][Rr][Ue][Ee]</pattern>
</bind>
     <bind><value> 0 <value>  <pattern> [Ff][Aa][Ll][Ss][Ee] </pattern>
</bind>
     <bind><value> 1 <value>  <literal> on </literal> </bind>
     <bind><value> 0 <value>  <literal> off </literal> </bind>
   </binding>
</datatype>

<-- Here the value space is the same but more acceptable lexical resp.
-->
<datatype name=?mySwedishBoolean?>
    <basetype name=?myBoolean?/>
  <binding>
     <bind><value> 1 <value>  <literal> sant </literal> </bind>
     <bind><value> 0 <value>  <literal> falskt </literal> </bind>
   </binding>
</datatype>

<-- Enumeration -->
<datatype name=?enum?>
  <basetype name=?integer?/>
</datatype>

<datatype name=?myByteColor?>
  <basetype name=?enum?/>
    <minInclusive>0</minInclusive>
    <maxInclusive>255</maxInclusive>
 <binding>
     <bind><value> 0 <value>  <literal> white </literal> </bind>
     <bind><value> 255 <value>  <literal> black </literal> </bind>
   </binding>
</datatype>

<datatype name=?mySwedishByteColor?>
  <basetype name=?myByteColor?/>
 <binding>
     <bind><value> 0 <value>  <literal> vit </literal> </bind>
     <bind><value> 255 <value>  <literal> svart </literal> </bind>
   </binding>
</datatype>
