`boolean` | `isElementAvailable(java.lang.String qname)` Determine if an extension element is available
`boolean` | `isExtensionNamespace(short uriCode)` Determine whether a given URI identifies an extension element namespace
`boolean` | `isFunctionAvailable(java.lang.String qname)` Determine if a function is available
