- new methods for MetaSlot to factor out common code: + slotName (to ease name-construction, care about slot container) + createFromParameterSyntax: essentially move from ::xotcl::Attribute to the meta class - test environment: make sure to avoid confusions between the "namespace" method and command
- added "multivalued" to parameter options - made error message produced by XOTclObjErrType look like Tcl's error messages - extended regression test - test utility: changed "?" to return error msg in case of error
