The category.xml is only an authoring format. In the end, the
categories are represented by IUs (InstallableUnit) that are part of the
metadata repository (content.xml). Theses IUs are generated by the 'Category
Publisher'. Like any IU those can be access by querying the repository. The
query can be created using the following: QueryUtil#createIUCategoryQuery.
