@mqliquid, the statements on the talk page are not binding, the statements on the wiki page are. The entire talk page can be disregarded, but whatever is derived from there and put on the wiki page, holds as binding (which makes perfect for Talk pages as a place for debate). Therefore, the entire paragraph in the wiki (also if based on the unbinding Talk statements) is valid and binding.

And according to that paragraph, as it is written now, "the contents of the sign, as it would be *read* from beginning to end" is to be provided.

Moreover, the https://wiki.openstreetmap.org/wiki/Invalid_Abbreviation_Expansion doesn't provide any example for German abbreviation "St." resolving to "Sankt" but only the English ones resolving to "Saint".

Furthermore, it doesn't matter whether "St." (read as "Sankt") is an abbreviation or not, since the "Value" paragraph of "Key:destionation" only focuses on the "be the contents of the sign, as it would be *read* from beginning to end".
