Identifiers

The identifier used here is different from the "church code" on the pages, and looks like it can only found in the source code. The church code seems to be from churchinwales.org.uk, which has (for example) https://www.churchinwales.org.uk/en/structure/church/3553/ - is there an identifier for this? Not sure of the best way to explain this, but it should be mentioned somewhere as I assumed it was the church code and only found it was different when checking the link. It's possible that there are already incorrect values if links have not been checked when adding this identifier. Peter James (talk) 19:40, 4 February 2020 (UTC)
