Description
4 JCK tests (idI021.xsd, idJ029.xsd schema attached) use the xpath expression '. //.' in a selector and in a field. Although the specification (http://www.w3.org/TR/xmlschema-1/#coss-identity-constraint) states: -------------------------------------------------- For readability, whitespace may be used in selector XPath expressions even though not explicitly allowed by the grammar: whitespace may be freely added within patterns before or after any token. ... Lexical productions [5] token ::= '.' | '/' | '//' | '|' | '@' | NameTest [6] whitespace ::= (#x20 | #x9 | #xD | #xA)+ When tokenizing, the longest possible token is always returned. -------------------------------------------------- The parser ( schemaFactory.newSchema( schemaSources ) ) fails with exception c-general-xpath: The expression '. //.' is not valid with respect to the XPath subset supported by XML Schema.
