<template> elements have no helper

[steve-h]

I was contemplating Bootstrap Vue to see if it fit with this library.

I noticed that the <template> element is not handled in the library helper functions. It is sort of a fragment "thing" but is distinct in that you may possibly exclude it from being modified as it is not actually displayed in the main DOM, (ex. the redact example)

There should at least be example documentation on how it should be coded as an element and allowed in the document / fragment.

elements rb,rtc,data also do not appear in the Tag enum?
