The top sitemap *should* handle the error and IIRC it did, but I had to make
the reference to the stylesheet in the root sitemap be resolved with
context:// .
AFAIK the subsitemap uses the first available parent sitemap handle-errors
resolving relative to its own context.

You should declare the handle-errors in the sub sitemap and handle them
there, or leave it all to the root sitemap.

As with all actions, when the action fails, it continues processing outside
of itself.
This is how it could work:
<map:match pattern="**.xml">
<map:act type="lang-select">
<map:act type="resource-exists" url="{../1}_{lang}.xml">
<!--if it doesn't fail, it executes what's in here -->
<map:generate src="{../../1}_{../lang}.xml"/>
<map:serialize type="xml"/>
</map:act>
</map:act>
<!--if it fails, it executes what's here -->
<map:generate src="failerrormessage.xml"/>
<map:serialize type="xml"/>
</map:match>
