Re: [xml-dev] Facet of simpleType

[Martin Gudgin <marting@develop.com>]

Because all the facets apart from pattern work on the value space of a type
rather than the lexical space of a type there is no way to do this with
facets such as totalDigits because the lexical forms 12345 and 000000012345
map to the same point in the value space. Pattern works on the lexical space
so you could say

    <xsd:simpleType name='Only8Digits'>
      <xsd:restriction base='xsd:decimal' >
        <xsd:pattern value='[0-9]{8}'/>
      </xsd:restriction>
    </xsd:simpleType>
