A variation on a common theme here: AA literals aren't constants and can 
therefore not be used as initializers for global variables.
Also, struct literals not directly used as initializers can't use the '{ 
<members> }' syntax.

Try this instead:
---
HASHTAG[string] tags;
static this() {
     tags = ["(0002,0000)": HASHTAG("UL","N","Group Length")];
}
