@xmlaspect/reactive-xml - reasons of creation

For ApiFusion the import documentation from sources into MediaWiki pages become a sequence for processing various data from different sources, mostly data and html web services. This mix when implemented with classic asynchronous patterns like callbacks, Promise call chain, or `async` JS keyword become a spaghetti code mess hard to code and maintain.

An another use case inspired reacive-xml creation is a web crawling for data mining. In my case finding who will share the floor on various dance competitions.
