Passing arguments to a node with an alias url There is a similar issue in here:
Passing an argument to a node causes 404

But there is no real viable solution.
I tried using the sub-pathauto module but the restiction of 8 arguments is too little, since the urls will look something like this:

www.site.com/alias/key/value-1/key/value-2/key/value-3/key/value-4

and it can go on for a while.
It works when instead of alias i have node/nid.

Is it possible to have it work with any amount of dynamic arguments?
Iv'e not tested with more than 8 args, but I enabled path_alias_xt when passing args to a node Alias with /mynode/term-name/tid and the 404s magically went away.

Further more using
print_r(arg(2));
in the node template prints "term-name"
