Where are newer versions of magnet specs? I can't believe it's still
v0.1 after six years


=2=
Where are newer (than v2.2) versions of magma specs? I've seen
references to v4.0

How to interpret these:

both kt and xt are specified:
magnet:?xt=urn:sha1:blah&kt=foo+bar

both mt and xt are specified:
magnet:?xt=urn:sha1:foo&mt=http://bar.org/baz.magma


=4=
Which of these are correct?

.0 suffix. I'm assuming that .1 IS correct:
magnet:?xt.0=urn:sha1:blah

.foo suffix (are non-numeric suffices valid?):
magnet:?xt.foo=urn:sha1:blah

.number suffix for custom parameter:
magnet:?x.myparam.1=blah

=5=
Should a manifest topic (pointed by mt) be in magma format, or any
format is permitted?
