I'm putting together a simpler test case for this, but I figured I'd start by asking the question and seeing if the answer is simple...
I have an XML document with the date elements:
                <documentDate>20080808</documentDate>
                <entryDate>2009-09-22</entryDate>the documentDate is defined as PartialDateType.
     <xsd:simpleType name="PartialDateType">
          <xsd:restriction base="xsd:string">
               <xsd:pattern value="\d{4}|\d{6}|\d{8}"/>
          </xsd:restriction>
     </xsd:simpleType>When I try to validate the document, I get
“literal "20080808" is not valid with respect to the pattern”.
If I shorten the date to "2008", the document validates.
What part of <xsd:pattern value="\d{4}|\d{6}|\d{8}"/> do I not understand?

Answer 1

Workaround is to reverse the pattern.. See below
