I noticed this while I was catching up on the XML protocol: "...extend the Sitemaps protocol using your own namespace." Click here to view the reference (sitemap.org).
What extra functionality does this provide, and why is having your own namespace important?
This is a new area for me, and I'd like to build my skillset... with this community's help!
What I'm wanting to do is create a vertical accordion menu for a large site I manage. The tool I use can create a menu, but it also doesn't allow me full control in all situations. So, I'm looking for ways to reliably and successfully create my own menu using the data I already have.
