Allow XML namespace prefixes for inky tags

[cumuru]

I‘d really like to be able to prefix all inky tags with an XML namespace (like <inky:columns>). The current workflow of many of our email project is 1. create template with Foundation for Emails and 2. integrate it in a CMS. Along this path a XML prefix with corresponding XSD would ease hacking (IDE autocompletion) and validation (be it IDE or CI or the like).
What I tried is overriding component registry with namespaced tags (like inky\\:columns) but it would exceed maximum call stack - no clue why. I‘m no pro in cheerio nor node in general, so any help is appreciated.
btw: Thanks for Inky and for sharing it!

The PHP based part is ready, just in case I didn‘t make clear what‘s my goal:
