Use Case - Linking to a definition [RMarkdown Support]

Comment from @fmichonneau about handling links in RMd:

"We may want to provide more flexibility in the way the links are generated. For instance, we may need to provide options to switch between HTML or Markdown versions of the links. For the HTML version using the htmltools package might make it easier to provide additional attributes to the anchors."

gdef() is implemented, but we need to be more flexible around it.
