I don't know specifically about this syntax but that page translation breaks with such ugly parser functions is expected, see for instance https://www.mediawiki.org/wiki/Help:Extension:Translate/Page_translation_administration#Segmentation , "Parsing order". So I'd call this an enhancement.

It's not clear to me what you're trying to do. If you want to translate the noincluded instructions below, try placing the translate tag on its own line, and if it doesn't work use the usual manual subpage?

I tried to add <translate> </translate> into
https://meta.wikimedia.org/wiki/Template:Resolution_info/AffCom in this
way:

'''[[File:{{#switch:{{{status}}}|yes|passed|accepted=Yes
check.svg|rejected|no|failed|not accepted=X mark.svg|unknown|#default=Blue
question mark (italic).svg}}|15px]] <translate>Resolution
{{#switch:{{{status}}}|yes|passed|accepted=passed|rejected|no|failed|not
accepted=failed|unknown|#default={{{status}}}}} with {{{yes}}} votes in
favor{{#if:{{{no|}}}|, {{{no}}} votes against|}}{{#if:{{{abstention|}}}|,
{{{abstention}}} abstentions|}}{{#if:{{{noncast|}}}|, {{{noncast}}} votes not
cast|}} on {{{date}}}.<translate>'''

(I realize that that is super-ugly to translate, would have tried to refine
that in following edits)

Saving is not possible:

I don't see </translate>. You ended with "<translate>'", no closing tag.

Damn, I'm an idiot. Doing it properly works https://meta.wikimedia.org/w/index.php?title=Template%3AResolution_info%2FAffCom&diff=5514414&oldid=5237167
Whether it should be marked is another question of course, but I close this as resolved invalid.
