@Oscar_Orozco That would certainly be the intention.
The blocker is coming up with a coherent set of appearance names that work for the different mediatypes that need to have the ability to hide the choose button. A summary of that need is here. Please consider making a proposal in that thread.
That conversation turned into a discussion about a process for making changes to the form specification as requested by @issa. That conversation started at Formalizing process for ODK XForms spec changes but did not get much reaction. I'm not sure how to make progress from here. @yanokwa @martijnr any ideas? This is a relatively simple feature to implement and it would be great to get it in!
