Developing Custom Resolved Document Types with the Generated Document Types
The automatically generated resolved document for styling is a DTD. The automatically generated resolved document type for editing is an XML schema. You can explicitly generate either of these document types to use as the basis for a custom resolved document type. It is not recommended that you develop a custom document type for the resolved document for styling. However, you might want to create a custom resolved document for editing so that it opens faster.
The following ACL functions enable you to generate a resolved document type:
dita_rds_dtd_from_map
dita_rde_xsd_from_map
Follow these steps to develop a custom resolved document type with generated document type:
1. Create a DITA map that contains a reference to every DITA map, topic, and ditabase that you plan to use in your documentation.
2. At the command-line, enter either dita_rde_xsd_from_map(current_doc(), "filename") to generate an resolved document for editing XML schema or dita_rds_dtd_from_map(current_doc(), "filename") to generate an resolved document for styling DTD.
3. Create a document type directory for the resolved document and copy the generated file there.
4. Add the catalog, .dcf, and other document type files for your new document type.
5. Update your DITA map’s .dcf file to point to your new resolved document type.
