Schema Based Problems

[jaybytez]

I am a rookie to schemas and am having some validation type issues with a schema. Could someone tell me what it looks like I am doing wrong within this schema? Thanks.

<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?>
<xs:schema xmlns:xsd=&quot;

Firstly I would always be explicit with the minOccurs it can solve many spurious errors.

Secondly, you have the wrong xmlns - it should be:

<xs:schema xmlns:xs=&quot;[URL unfurl="true"]http://www.w3.org/2001/XMLSchema&quot;[/URL] elementFormDefault=&quot;qualified&quot; attributeFormDefault=&quot;unqualified&quot;>

Thirdly,

In all cases of an XML element that you have attributs you MUST wrap the attributes within an <xs:complexType> tag e.g.

<xs:element name=&quot;field&quot; maxOccurs=&quot;unbounded&quot;>
      <xs:attribute name=&quot;name&quot; type=&quot;xs:string&quot; use=&quot;required&quot;/>
      <xs:attribute name=&quot;value&quot; type=&quot;xs:string&quot; use=&quot;required&quot;/>
    </xs:element>

Should be:

<xs:element name=&quot;field&quot; maxOccurs=&quot;unbounded&quot;>
  <xs:complexType>
      <xs:attribute name=&quot;name&quot; type=&quot;xs:string&quot; use=&quot;required&quot;/>
      <xs:attribute name=&quot;value&quot; type=&quot;xs:string&quot; use=&quot;required&quot;/>
    </xs:complexType>
</xs:element>

Hope this helps,
