Domestic Hot Water example is incomplete

[Besjan]

domestic-hot-water.ifcx file is missing the element with id "2a22c4a4-48a6-54a1-bdc7-ccc1af978446" that is being referenced from all "partofsystem" relationships, e.g.:

{
  "path": "5b477df7-581a-4bab-b94c-7ab539a932d1",
  "attributes": {
    "bsi::ifc::system::partofsystem": [
      {
        "ref": "2a22c4a4-48a6-54a1-bdc7-ccc1af978446"
      }]
  }
}

Can you also in ifc5 easy to implement and use generator of unique id so be easy implement in all languages like swift JavaScript c this would ifc generation multi platform

@Besjan thanks for reporting, really encouraging to see this kind of in-depth review of the samples.

This is now fixed by patching the ifc4 to ifc5 conversion script.

@Isaina the id / path components you see in ifc5 are supposed to be valid rfc4122 guids, so there is little work needed on this front https://datatracker.ietf.org/doc/html/rfc4122
