A lot of data is retrieved from the .item-XML file a TOS job contains. To optimize queries against this file, it should be loaded once when starting the XMLHelper and made accessible via "native" Java components (e.g., which is used at many points already Properties). For version 0.3, the .item-XML file-handling should be reworked to be more flexible regarding queries and allowing to modify it, e.g. to add hidden components to it virtually.
