The entire Bregenzerwald is made up of hundreds of small hamlets, which are gradually being grouped together into village associations. The hamlet of Melisau was grouped into the municipality of Egg. In order to be able to correctly read the GIS in Austria, it is necessary to become familiar with the operation there, as it is not possible to insert unnamed residential roads in the GIS. For this reason, all residential roads throughout Austria always have a name, which is incorrect in reality. In order for "addr:street" to be used, a physical street name on a sign is required. See example: https://commons.wikimedia.org/wiki/File:Haselstauden-Stra%C3%9Fenschilder.jpg
Respectively, the name must have been dedicated to the street. This is not the case here, there is no sign. The hamlet is called "Melisau", so "addr:place" was already correct before.

It is correct that the addresses here are "Melisau 123, 6863 Egg", but Melisau is not a single street, but the entire village. I am therefore changing it back so that it matches the more than 100 other villages with the same system. Thank you.
