I see a lot of confusing information about how to create a link in your structured Frame file to a pdf file. I've tried several different approaches and none seem to work. One topic mentioned inserting a hypertext element in a prepared area, but I can't find any information about how to prepare that area, nor could I find information about when a hypertext element is available and valid for use. I also tried inserting as an xref with a relative path, and attempted to add the pdf to the ditamap and other embarrassing ideas.
What is the best, easiest way to have an external pdf open from a pdf generated from structured frame file?
