Support multiple values for survey_point:structure=*

[jidanni]

Alas, block;plaque needs to have the ;plaque part manually typed in, as there is no way to multiselect from this menu. Yes I tried CTRL+click.

I'll transfer this issue to id-tagging-schema, but only 3 out of 23,000 features in the database have a semicolon (0.01%)¹, so I'm not sure if this should be changed.

I would say it sounds fine to keep it for manual tag editing then
