Yes, this is a documented ``specificity'' of xsdvalid. See http://www.xmlmind.com/xmleditor/_distrib/docs/xsdvalid/xsdvalid.html#id.s6.2: ------------------------------------------------------------------------------- * A import construct must almost always specify a schemaLocation [x-src-import]. However, the validation engine supports xs:import elements without a schemaLocation attribute, if an xs:import element for the same namespace but this time having a schemaLocation attribute has previously been processed. Example: +----+ <xs:import namespace="foo" schemaLocation="http://foo.com/schema1.xsd" /> <!-- Later, typically inside an included module. --> <xs:import namespace="foo" /> +----+ -------------------------------------------------------------------------------- What follows is legal W3C XML Schema; useless for xsdvalid but legal: +----+ <xs:import/> +----+ Therefore, we need to turn "x-src-import" errors into *warnings*. This will be done in next release.
