This is new in JAXP 1.2

JDOM Beta 8 has introduced a SAXBuilder.setProperty to help avoiding this.

Neither Xerces 1.4.x nor Xerces 2.1.0 support JAXP 1.2 and Crimson (included 
in JDK) does not validate against schemas.

While waiting for Xerces to support JAXP 1.2, you could use Xerces' 
proprietary properties: 
"http://apache.org/xml/properties/schema/external-SchemaLocation" and 
"http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation".
