>                 URL: http://issues.apache.org/jira/browse/JCR-579
>             Project: Jackrabbit
>          Issue Type: Bug
>          Components: query
>    Affects Versions: 1.0.1

> INTRODUCTION:
> According to JSR-170-ch.4.6"Path Syntax" a syntactically valid path is:
> ...
> name ::= [prefix ':'] simplename
> simplename ::= onecharsimplename | twocharsimplename | threeormorecharname
> onecharsimplename ::= /* Any Unicode character except: '.', '/', ':', '[', ']', '*',
''', '"', '|' or any whitespace character */
> ...
> So, any "digit' name (e.g. "my:777") sould be valid.
> WHAT I DO:
> import org.apache.jackrabbit.core.query.*;
> ...
> String q = "/jcr:root / 2 / ( *, mytype)";
> QueryParser.parse( q, "xpath", nsRegistry);
> WHAT I EXPECT TO HAVE:
> Succesfully parsed query.
> WHAT I GET:
> javax.jcr.query.InvalidQueryException: Parse error: data is not a RelationQueryNode
