`xref` links to other .adoc files results in incorrect link in eleventy HTML output

[wu-lee]

Problem

The AsciiDoc documentation advises the use of xref macros instead of link or http macros for linking to other AsciiDoc files:

https://docs.asciidoctor.org/asciidoc/latest/macros/link-macro/#link-to-a-relative-file

If you want to link to a non-AsciiDoc file that is relative to the current document, use the link macro in front of the file name.

Tip: To link to a relative AsciiDoc file, use the xref macro instead.

Unfortunately if we try that in the context of this plugin, you get a link to the wrong place.

Example

Given _src/index.adoc content like this:

= Home page

Link to xref:page1.adoc[page 1]

And _src/page1.adoc:

= Page 1

content here

Link back to xref:index.adoc[home page]

Then the resulting link in _site/index.html will be to page1.html. It should be to page1/index.html.

The link in _site/page1/index.html will be to index.html. It should be to ../index.html or perhaps /index.html.

Workaround

The obvious workaround is to ignore the advice and use link macros. But possibly this could be fixed simply? Is there a configuration which adjusts this behaviour? This would allow AsciiDoc files which follow the advice to be imported for use in Eleventy without needing adjustment.
