Dear Tim,
I hope you have been fine.
Would you mind me asking a quick question again?
I checked the Arbortext Help Centre and found an article about custom folder and its subdirectories.
In that article, it seems that custom/application was not mentioned. (See "Description of the custom directory structure".)
Therefore I came up with a structure in reference to "techinfo" folder. Do you think the following structure is good?
application
+- com.arbortext.specialization
|- dcfmodules
| +- specialization-base-module.dcf
|- ditarefs
| +- specialization_topic_sample.dita
+- doctypes
|- catalog
|- specialization.dcf
|- specialization.dtd
|- specialization.pcf
|- specialization.style
|- specialization_topic.dtd
|- specialization_topic.ent
+- specialization_topic.mod
I hope to hear from you.
Kind regards,
Tomomi
