I maintain a .page.xml for all pages in my app. Two of the pages have long lists of parameters, which must match. I've been maintaining two separate lists in List1.page.xml and List2.page.xml, but I'm wondering if there is a better way.
Can I put these params in global pages.xml? I think I tried it once long ago and it did not work.
Or can I source a file into the .page.xml so I can maintain 1 copy of this parameter list elsewhere?
You can place any pagedefinition also in pages.xml at the global level. I prefer doing this - even with large numbers of pages - because it keeps everything a one single location.
