Ah, I know what's doing that, but see below for more on this...

That refers to the keyword or name part of a name/value pair, whereas
in the above it's actually in the value part. However, 2 things spring
out of this:
1) I'm not clear if there are certain characters that are invalid in
an address string, other than space characters.
2) xAPFramework lets dodgy characters through in the name/keyword part
anyway!!! I'm amazed I've never spotted that before!!! For example:

Display.SliMP3
{
Line1%=Hello
Line2=World!
Duration=15
}

Anyway, how well does a percentage sign sit in an address value? If I
decode the escaped characters in this particular case I will end up
with a definitely invalid address. For instance:

Source=KCSoft.SliMP3.Anya:Test:Me

So in this respect I actually think that Test%3aMe is correct, strange
as it may seem. I'm back to what do I do with somewhat more wilder
names assigned for players.

Also space characters work out okay sticking with this mechanism as
they turn up as "Test%20Me".

Dotted separators are fine as you've discovered e.g. "Test.Me"
with
the proviso that they are interpreted as sub-subaddress nodes as per
the xAP spec.

So the question is are % characters allowed in header values in this
way? I had a gander at the spec but I couldn't spot any rules on this.
May have missed it though as I was scanning.

You have helped find a bug in xFx though, where it's not stringent
enough. Darn. d;-))
