Remixml, javascript module

This might be of interest to the Pike and/or Roxen community:

https://www.npmjs.com/package/remixml

I just launched it.
Using it in a Single-Page-Application website.
Any critical feedback is welcome (I'm currently the only user, so
changes in the API are easy and still allowed).

From the description:
Remixml is an XML/HTML macro language/template engine.

The language and primitives used blend in completely with standard XML/HTML
syntax and therefore integrate smoothly with existing XML/HTML syntax
colouring editors.

Requirements
It runs inside any webbrowser environment (starting at IE11 and up).

For historical reference:
Remixml was originally inspired by RXML, the Roxen webserver macro language.
