I’m investigating porting our 4.x docbook to 5.x. For our custom

makes it not DocBook, what are the pros and cons of namespacing our own
extension elements?
Namespacing means you avoid conflicts with any future DocBook versions.
As for the cons of not namespacing, I can't think of any other than the
extra typing it requires. Aren't all XML parsers worth talking about
namespace aware now?
That rhetorical sweep includes old versions of modern parsers that are
still available in "stable" OSes like RHEL and Debian. MSXML -- made by
the company that never met a standard they didn't want to wreck -- has
supported namespaces going back to the XP days, a dozen years ago at least.
