Can lemminx be extended?

[laeubi]

Sometimes a maven mojo configuration can contain domain specific languages, for example the bnd-maven-plugin supports embedding of bnd-instructions:

<plugin>
    <groupId>biz.aQute.bnd</groupId>
    <artifactId>bnd-maven-plugin</artifactId>
    <configuration>
        <bnd><![CDATA[
            -exportcontents:\
                org.example.api,\
                org.example.types
            -sources: true
        ]]></bnd>
    </configuration>
</plugin>

of course lemminx could not understand these, but I wonder if it is possible to add support for such things via a lemminx extension somehow?

So what I want is:

1. Syntax highlighting of the domain specific language
2. Providing validation
3. Having autocompletions
4. Add code-minings

Yes, of course lemminx itself can be extended, especially since lemminx-maven is one of such extensions. See https://github.com/eclipse/lemminx?tab=readme-ov-file#extensions for details.
Such bnd extension could have lemminx-maven as dependency.

Thanks I think that looks like what I was looking for!
