Xopus next release?


Trying Xopus 5.4.2 to port old legacy code from Xopus running on Exist-db I met some anomalies:
- document() in XSLT is still restricted to Internet Explorer
- <xi:include href="{$path}"/> is fetched as %7B$path%7D, without replacing the XSL variable (document /%7B$path%7D not found)
- Xsd are sometimes badly applied, not showing all options
- html files are poorly formatted, without closing tags mixing upper and lower case in the tags.
- Safari is still not supported.

Will these anomalies be corrected in a future version?
Or will the source code be open sourced to allow corrections?
Or is the code frozen?
