SchemaFactory doesn't support W3C XML Schema in platform level 8?

Question

With the Android SDK, the following code in a plain empty Activity fails:

@Override
protected void onStart() {
    super.onStart();

    SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
}

The 2.2 emulator logcat shows this exception:

The Javadoc of SchemaFactory mentions "Platform default SchemaFactory is located in a implementation specific way. There must be a platform default SchemaFactory for W3C XML Schema."

Same here. I have added this to Googlecode Android Issues.
