The SDO spec will be addressing standard instance properties that allow
values of facets to be retrieved from types and properties. Until that time
it allows implementations to define their own, adn we do that in Tuscany.
See
http://svn.apache.org/repos/asf/incubator/tuscany/java/sdo/impl/src/test/java/org/apache/tuscany/sdo/test/MetadataInstancePropertiesTestCase.java
You can uncomment the lines of code that print out the values of instance
properties. My initioal digging around suggests that this is the set of
Properties we support.
"minExclusive"
"minInclusive"
"maxExclusive"
"maxInclusive"
"totalDigits"
"fractionDigits"
"length"
"minLength"
"maxLength"
"enumeration"
"whiteSpace"
