Michael:
Thanks for the response. I assumed that xs:anyType and a content type
of mixed was the "most general" substitution if it couldn't find the
schema. However, I am using an entity resolver. Here is how I
created and configured my grammar preparser:
grammarParser = new XMLGrammarPreparser();
grammarParser.registerPreparser(XMLGrammarDescription.XML_SCHEMA, null);
grammarParser.setFeature(Constants.XERCES_FEATURE_PREFIX +
Constants.NAMESPACE_PREFIXES_FEATURE, true);
grammarParser.setFeature(Constants.NAMESPACES_FEATURE, true);
grammarParser.setFeature(Constants.SCHEMA_AUGMENT_PSVI, true);
grammarParser.setFeature(Constants.SCHEMA_ELEMENT_DEFAULT,
true);
grammarParser.setFeature(Constants.SCHEMA_FULL_CHECKING, true);
grammarParser.setFeature(Constants.SCHEMA_NORMALIZED_VALUE,
true);
grammarParser.setFeature(Constants.SCHEMA_VALIDATION_FEATURE,
true);
grammarParser.setFeature(Constants.VALIDATION_FEATURE, true);
String grammarPoolProperty0 =
Constants.XERCES_PROPERTY_PREFIX + Constants.ENTITY_RESOLVER_PROPERTY;
grammarParser.setProperty(grammarPoolProperty0,
catalogResolver);
String grammarPoolProperty = Constants.XERCES_PROPERTY_PREFIX
+ Constants.XMLGRAMMAR_POOL_PROPERTY;
grammarParser.setProperty(grammarPoolProperty, new
XMLGrammarPoolImpl());
I checked my catalog resolver and was pretty sure that was right. I
was still worried that I had done something wrong, so I added the
location of the second schema to the first, using the following:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.grs.com/WayptSchema ./
waypt.xsd"
The mission and waypt schemata are in the same directory, and I tried
it with both relative and absolute paths. Still the same problem. Is
it possibly something wrong with my configuration of the grammar
preparser?

Hi Mark,
There's an error message that you're probably ignoring which would
be complaining about not being able to resolve "wp:WayptType". When
a type definition cannot be found Xerces recovers from this error by
assigning xs:anyType as the type of the element. You do have an
import in the first schema document but it has no schema location
hint (e.g. schemaLocation="file:///some/uri). Therefore the schema
loader would have no idea where to find the other schema document
unless you register an entity resolver that knows how to locate it
based on the namespace "http://www.grs.com/WayptSchema";.
Thanks.
