Support comparison of properties in queries (on both sides of comparison)
-------------------------------------------------------------------------

                 Key: JCR-1146
                 URL: https://issues.apache.org/jira/browse/JCR-1146
             Project: Jackrabbit
          Issue Type: Improvement
          Components: query
    Affects Versions: 1.3.1
            Reporter: Amir Mistric


Currently Jackrabbit does not support having properties on both sides of a comparison in a
query.

For example, neither one of the following queries return results (and they should)  nor they
throw an exception!!!

1. /jcr:root/www-mysite-org//element(*,mgnl:content)[MetaData/@mgnl:activated='true' and MetaData/@mgnl:lastmodified
> MetaData/@mgnl:lastaction] 
2. /jcr:root/www-mysite-org//element(*,mgnl:content)[MetaData/@mgnl:activated='true' and xs:dateTime(MetaData/@mgnl:lastmodified)
> xs:dateTime(MetaData/@mgnl:lastaction)]
3. /jcr:root/www-mysite-org//element(*,mgnl:content)[MetaData/@mgnl:activated='true' and MetaData/xs:dateTime(@mgnl:lastmodified)
> MetaData/xs:dateTime(@mgnl:lastaction)]

The problem is that one of the comparison fields has to be literal which is very limiting...
