Re: XMLValidatingReader misses errors

Thanks for your interest. As you can see from the XML and XSD, I should get
an error on <Action> because "xxx" is not a valid value; there should be an
error because there is no <SubOrg> tag; and there should be an error
because <SubOrganization> is not part of the schema. As noted before, tags
like <abc></bcd> do generate an error, so I know something is happening.

Here is the XML:
strXML = "<Software>" & _
"<Action>xxx</Action>" & _
"<Organization></Organization>" & _
"<SubOrganization>DIOR</SubOrganization>" & _
"<SoftwareName>10</SoftwareName>" & _
"<Version>12</Version>" & _
"<Platform>12</Platform>" & _
"<ProductDescription></ProductDescription>" & _
"<ProductType></ProductType>" & _
"<Manufacturer>3</Manufacturer>" & _
"<DataSource></DataSource>" & _
"<Upgrades></Upgrades>" & _
"<Cost>0.0000</Cost>" & _
"<LicenseKey></LicenseKey>" & _
"<LicensePurchased>8</LicensePurchased>" & _
"<LicenseUsed>9</LicenseUsed>" & _
"<LicenseEmail1></LicenseEmail1>" & _
"<LicenseEmail2></LicenseEmail2>" & _
"<LicenseEmail3></LicenseEmail3>" & _
"<SWStart>1900-01-01T00:00:00</SWStart>" & _
"<SWExpire>1900-01-01T00:00:00</SWExpire>" & _
"<PhysicalMedia>" & _
"<MediaType>CompactFlash</MediaType>" & _
"<BarcodeNumber>44</BarcodeNumber>" & _
"<NumberOfDisks>44</NumberOfDisks>" & _
"<LicenseKey>44</LicenseKey>" & _
"<OfficeLocation>44</OfficeLocation>" & _
"<DataSource>44</DataSource>" & _
"</PhysicalMedia>" & _
"</Software>"
