When Saxon-SA is used with validation=strict, any attempt to read the catalog file used by the standard collation URI resolver will fail on the grounds that there is no schema.
There is no schema supplied for this file, and as it does not use a namespace, it could be operationally convenient to load one. So the code is being changed to skip validation of the catalog.
Although this is a problem only for Saxon-SA users, the relevant code is in the StandardCollectionURIResolver in Saxon-B code. A patch is therefore being raised in the SourceForge SVN repository.
