About @epa-wg/custom-element

@epa-wg/custom-element is a Declarative Custom Element implementation based on HTML template and XSLT syntax. Template rendering takes data and XSLT to be transformed into HTML. As those are not easy to explore on the web page, developer would benefit of "Transformation" tab in the DOM inspector. In addition to transparent view into data and template plugin allows to copy both into the files to debug the template step-by-step in IDE.
