Crew View and Dynamic Documents - Windchill

I am currently investigating Creo View and its capabilities. I have a few questions.

- Can Creo View be launched from Windchill on a dynamic document (ex. - xml, png)?

- Can Creo View be launched from Windchill if the document was created in ArborText?

- What is Creo View Standard and how is it different than the other view types (MCAD, ECAD, MCAD+ECAD)?

- To annotate anything, is there an add-on that needs to be installed?

Any help would be greatly appreciated.
