It should be simple, I corrected this a couple of times before. It's just the copyright header at level 2 that's missing. See e.g. https://github.com/eclipse-ee4j/authorization/blob/master/spec/src/main/asciidoc/license-efsl.adoc#copyright

It looks like the WARN regarding the character issue was introduced as part of de2deae#diff-16b376b1e09deeb28d3bfb443bc6e7d6 as far as I can tell.

I'm working through that change to see what happened and correct it as well as part of this issue.

Regarding the character issue I can't for the life of me determine why asciidoc complains about this. Looking at the rendered code it looks to be 100% correct. For now I think we can leave it be as it looks to be caused by the footnote in the literal block but it renders successfully as far as I can tell.

[pnicolucci]

If I were to use a literal block sub of macros+ rather then +macros I can see the footnote syntax added in the pdf and that is:

<x:parse {doc="XMLDocument"|xml<a id="_footnoteref_10">􀀀</a><sup>[<a
anchor="_footnotedef_10">10</a>]</sup>="XMLDocument"}
{var="var" [scope="scope"]|varDom="var"
[scopeDom="scope"]}
[systemId="systemId"]
[filter="filter"]/>

You can see there is an odd character but it doesn't render in the final product using +macros substitution but we still get a warning it seems. Perhaps this is a bug with asciidoc?

[arjantijms]

@pnicolucci good find. I'm not sure if we absolutely need the footnote as it is. It would need to be handled in the next version of Jakarta Tags I think.

[pnicolucci]

The only remaining warning is:

[INFO] --- asciidoctor-maven-plugin:2.2.1:process-asciidoc (asciidoc-to-pdf) @ jakarta-stl-spec ---
