You would make changes to the template on Template:Infobox character. But, if you added, say, a "Blood type" field (with parameter name ), then it would not appear in the relevant documentation on Template:Infobox character/doc which is inconsequential besides its transclusion onto the main template page.

That would just mean that users looking at Template:Infobox character wouldn't know there was a blood type field unless they looked at the code or a page on which it was transcluded.
