I used JPA to validate this branch but generated some errors. Details here

@KazeemHamzat, I've made some further updates, would you mind retesting with JPA?

It is now passing validation but needs these two changes that I have added.
Issue 1
Removing Slicing from DiagnosticReport.category. It Should be inherited from the base. e.g,
"id": "DiagnosticReport.category",
"path": "DiagnosticReport.category",
"slicing": {
"discriminator": [
{
"type": "value",
"path": "coding"
}
],
Issue 2
This relates to non-compatible target profiles with Base.
