DITA: Unhiding props attribute in dita-base-module.dcf has no effect
Just temporarily, we'd like to be able to show the props attribute in the Modify Attributes dialog box (CTRL-D). We realize that this is used for specialization only, but we've created a migration that uses it directly for now.
I edited the file C:\Program Files\PTC\Arbortext Editor\application\com.arbortext.dita\dcfmodules\dita-base-module.dcf
Making this change on 5.4 M050 worked for me, though I did it a little differently. I always try to avoid modifying any of the files distributed with the software, to avoid issues when upgrading to a newer version. Editor's Custom Directory feature helps a lot with this.
In this case, I copied the dita-base-module.dcf file into the "doctypes" directory in my custom folder, made the modifications to that copy, then copied the line ending with "dita-base-module.dcf" from the "dcfmodules/catalog" file to the "catalog" file I had in my "doctypes" directory.
If this change isn't working, it's possible that your configuration is somehow bypassing the dita-base-module.dcf file. From within a DITA topic where this isn't working, try selecting "Help -> About Arbortext Editor -> Session" from the menus. In the resulting dialog, select the "Document" tab and look at the value for "Doctype configuration". This should be the full path to the DCF file actually being used.
