We are working on a migration project to migrate content from Drupal to AEM using DITA xml files. Currently, there's a task to explore how AEM consumes the metadata contained in these xml files. Mainly, there's a need to add page properties in a ditamap. This, however, is not to be done manually (via page properties tags in AEM), which is why, we have to come up with a way to add cq:tag attribute somehow in the ditamap xml file. This is to ensure that page properties are directly consumed by AEM when the ditamap is uploaded and converted to an AEM Site.
