In Knowledge Center, the ISHPublDITAOTUtil.vbs controls how files are renamed during DITA-OT processing. This code gets called regardless of whether you are using a transtype in the InfoShare version of the DITA-OT or a custom version.
In Tridion Docs, is see no equivalent in the Data/Publishing folder. We have one output format that uses the transtype ishpdf, and it properly renames the ditamap file extensions. Our other transtype is a custom PDF plugin. The extension renaming routine does not get called, so the mapref-check never happens, and the PDF comes out with no content.
Where is this routine stored, and how can I get it to run properly for our custom plugins?
TIA
