Description

SaxonJS doesn't yet allow users to supply their own URI resolver.

I came across the need for such a feature while trying to make resources stored in browser local storage (IndexedDB) available to XSLT running in the browser. I was hoping to be able to supply a resolver that would allow me to handle indexeddb: URIs.

I tried using the browser's "Service Worker" functionality, which can intercept the browser's "fetch" requests, and then either allow them to be handled normally, or else return a promise to fulfill them in some other way. Unfortunately I found that approach is applicable only to URI schemes which the browser already knows about (e.g. http, https, file ...) and also is constrained by some irrelevant security restrictions.
