Oracle's Schema Processor is failing to catch errors

Question

I tried validating an XML document with known errors against a valid schema using Oracle's Schema Processor v0_9_0_0 and did not get the expected results.
I used the following test file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<Cars xmlns = "http://www.CarDealers.com/"
xmlns:xsi = "http://www.w3.org/1999/XMLSchema/instance"
xsi:schemaLocation = "http://www.CarDealers.com/ Store.xsd" RequestDate="ashd">
<Model>Ford</Model>
<Make>ExplorerExpeditionTaurusF150Escort</Make>
<Year>1999</Year>
<OwnerName>Joe Smith</OwnerName>
<OwnerName>Bob Jones</OwnerName>
<Condition Automatic="NA">Small dent on right bumper.</Condition>
<Mileage>400000000</Mileage>
</CarDealers>
And validated the sample against the following schema:
<?xml version="1.0" encoding="ISO-8859-1"?>
<schema xmlns = "http://www.w3.org/1999/XMLSchema"
targetNamespace = "http://www.CarDealers.com/">
<element name="Car">
<complexType>
<element name="Model">
<simpleType base="string">
<enumeration value = "Ford"/>
<enumeration value = "Saab"/>
<enumeration value = "Audi"/>
</simpleType>
</element>
<element name="Make">
<simpleType base="string">
<minLength value = "1"/>
<maxLength value = "30"/>
</simpleType>
</element>
<element name="Year">
<complexType content="mixed">
<attribute name="PreviouslyOwned" type="string" use="required"/>
<attribute name="YearsOwned" type="integer" use="optional"/>
</complexType>
</element>
<element name="OwnerName" minOccurs="0" maxOccurs="unbounded"/>
<element name="Condition">
<complexType base="string" derivedBy="extension">
<attribute name="Automatic">
<simpleType base="string">
<enumeration value = "Yes"/>
<enumeration value = "No"/>
</simpleType>
</attribute>
</complexType>
</element>
<element name="Mileage">
<simpleType base="integer">
<minInclusive value="0"/>
<maxInclusive value="20000"/>
</simpleType>
</element>
<attribute name="RequestDate" type="date"/>
</complexType>
</element>
</schema>
The Oracle parser did not recognize the W3C facet syntax of minLength and maxLength; the file would pass validation if I changed the syntax to minlength and maxlength.
The Oracle parser did not recoginze the W3C "use=" syntax used for attribute occurrences; the file would pass validation if I changed the syntax to minOccurs and maxOccurs which should be used for element validation only.
The Oracle parser did not recoginze the W3C "unbounded" syntax used to define max occurrences of elements; the file would pass validation if I changed the syntax to maxOccurs="*" .
The element "Year" was defined with a required attribute, PreviouslyOwned. However, the sample file is missing both the PreviouslyOwned and optional YearsOwned attributes and passes validation. It appears that the parser does not validate the presence of a required attribute unless another attribute is present for the element, e.g. if the optional YearsOwned attribute was in the file the parser would then catch that the PreviouslyOwned attribute was missing.
The sample file validated with an incorrect value of "ashd" for the RequestDate element, so it appears the "date" data type is not supported.
The parser does not recognize the "derivedBy" syntax used to define the Condition element. How else can you define the constraints for an elements value and attributes?
Based on some additional testing it appears that the Oracle parser cannot handle more than 4 or 5 include statements to reference other schemas.
Are these known bugs in the Oracle parser? Has Oracle issued any updates to this initial release? Are there any settings I should be aware of that may provide full er validation?

Hi OTM,
One of our Integration Subsystem is heavily depend on the schema processor for XML validation. 0.9 release - eventhough it is an Alpha, has proven to be very helpfull for us. We are looking forward to use the final release of this product, and expect it will completely support the W3C Schema Spec. I'm wondering when will be final relase availabe? Could you please give us a time limit for the new release? Thanks.

The current release is the initial one that is incomplete. Our second release is scheduled for the end of the month and will be much better.
