Description
params.json only supports defaults today. It should be possible to add appends and invariants
for example
{
"params":{
"my_param_set" : {
"a":"A",
"b" :"B",
"_appends_" : {
"c": "C"
},
"_invariants_":{
"d" : "D"
}}
}
In this case variables a and b are defaults, c is appends and d is invariants
The fact that we can have invariants and appends means that if a useParam is specified with the component, it should not be overridable from the request
So, this introduces a back incompat change

Noble Paul sweet! this will allow the workaround in example/files solrconfig.xml for /browse and the appended parameter.

Erik Hatcher From 6.0 onwards we are making this much needed change and params now have the full capabilities of standard requesthandler definitions.
