Since S1000D v4.0, the elements and attributes were changed to have a more descriptive naming convention. Authors, already familiar with the specification, could quite easily author a Data Module (DM) directly in the raw XML structure view.
However, when you move from the DM creation phase, where the XML structure is king, to the DM review phase, where the focus changes from structure to content , then there needs to be some sort of document layout. With a graphical authoring environment, both the Author and the Reviewer are able to focus on the technical content of a DM without being distracted by the underlying XML structure.
We understand that Authors can also need a physical PDF file for QA review by a Subject Matter Expert (SME) and/or submission to an Equipment Sponsor for final sign-off and approval. With our Docuneering vendor-neutral XSL-FO stylesheets, an Author can open a Data Module in their authoring software and create a PDF file with a single click.
As an indication of the output quality of our XSL-FO stylesheets, we have provided some PDF Sample files for customers to review.S1000D Demo files
