I am just looking at, or trying to get a feel for, all available options for "feeding" content into the data/text for use in the tour. Similar to an RSS feed where content is changed in one place and updated in another/others automatically. I just don't know what the full capabilities or limitations are of krpano for this typee of situation. Or if there are options other than a specifically dedicated XML file.
I am currently using a dedicated XML file for content on this project demo because there are multiple locations in the tour, each with their own description, and sharing a common css format. It is easier to manage the content separately rather than have it tied to the main.xml of the tour.
