Hi Ignacio, you can add your patch as an attachment to this JIRA issue. Since I could not find a Contributor License Agreement (CLA) on file [1] for you, you'll need to answer the contributor questions from section 7.3 of the Xerces Project Charter, available here [2]. We require this information to accept bug fixes from individuals who have not signed a CLA. The questions/answers can just be added to this bug report.
