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>
