Hello,

I would like to propose adding a syntax highlighting definition (XSHD) for HL7 v2.x messages.

HL7 v2.x is a widely used healthcare messaging standard. It is a plain text, pipe-delimited format (e.g. segments like MSH, PID, OBR, OBX, etc.), which makes it well-suited for regex-based highlighting in AvalonEdit.

I have a working XSHD definition that provides:

Segment highlighting (3-character segment IDs at line start)
Field and component separators (|, ^, ~, &)
Escape sequences (\...\)
Basic timestamp recognition

The implementation is minimal and does not introduce any breaking changes or additional dependencies.

Before submitting a pull request, I would like to confirm whether adding an HL7 definition to the repository would be acceptable from a project scope perspective.

If there is interest, I can open a PR with the proposed XSHD file.

Thank you.
