Hi, thanks for adding this.

However, please note that dashes are *never* used as crossing markings for pedestrian-only crossings of public roads in the UK and the permissible markings are prescribed by legislation (specifically TSRGD 2016).

The double dashed line transverse markings on side roads are give way markings, which are tagged as separate highway=give_way nodes. They have nothing to do with the crossing.

Crossings like this are usually crossing=unmarked + crossing:markings=no
