Although bug 18820 claims that now it's possible to hilight even the code containing <source>, it's not possible in every case. Template:Code {{#tag:syntaxhighlight|{{{code}}}|lang={{{lang}}}}} Article: Lorem ipsum {{Code|lang=xml|code= <image> <source isrelative="false">/absolute/path/to/image.png</source> </image> }} The example above triggers error.
Definitely not "lowest" priority as it breaks many pages already.
By using #tag the purpose is to allow wikitext expansion. That means {{{parameters}}}, {{#parserfunctions}}, {{templates}}, but also <tags>. If you don't want that, use <nowiki>: {{#tag:syntaxhighlight|<nowiki> <image> <source isrelative="false">/absolute/path/to/image.png</source> </image> </nowiki> |lang=xml }} .. which works as expected. Example: https://www.mediawiki.org/w/index.php?title=Project:Sandbox&oldid=541325 Invalid?
I think the solution of bug 18820 would be to use: <syntaxhighlight lang=xml> <image> <source isrelative="false">/absolute/path/to/image.png</source> </image> </syntaxhighlight>

But the bug here is that it needs to work through a template. And the only way to pass a template value to a tag is to use {{#tag:}} because <tag> will take {{{foo}}} literally.
(In reply to comment #2) <nowiki> causes no hiliting, so you can't wrap the content in it. If you'll find more effective way than {{Code|lang=xml|code= <image> <<nowiki/>source isrelative="false">/absolute/path/to/image.png</source> </image> }} how to put <source> in template parameter, I would be more than happy, thank you.
I'm afraid no better way is possible, and no better way will ever be possible. It's just a limitation of wikitext syntax. :(
