Please review http://www.ietf.org/internet-drafts/draft-blunk-rpslng-04.txt.
This clarifies the structured syntax for mp-import/mp-export attributes (and
the use of the "action" keyword). Some examples were also fixed to
be consistent with the syntax.

I would like to have your opinion on the following issues.
I beleive the last draft
http://www.ietf.org/internet-drafts/draft-blunk-rpslng-03.txt
has some serious typos.
Specifically in section 2.5 the definition of EXCEPT and REFINE do not
allow for nay curly bracket after the EXCEPT or REFINE .
mp-import ::=
[protocol <protocol-1>] [into <protocol-2>] <import-expression>
<import-expression> ::=
[afi <afi-list>] <import-term> accept <mp-filter> |
[afi <afi-list>] <import-term> accept <mp-filter> EXCEPT
<import-expression> |
[afi <afi-list>] <import-term> accept <mp-filter> REFINE
<import-expression>
<import-term> ::= <import-factor> |
{
<import-factor>
...
<import-factor>
}
<import-factor> ::= from <mp-peering> [action <action>];
While in the policy examples there are curly brackets after REFINE and
EXCEPT.
The second issue is with regard of the logic of REFINE and EXCEPT
statements.
Does the RPSLng REFINE statements refines the afi protocol list ?
if yes then this is not shown in the grammar.
Assume for example that I would like to express a policy like
import from AS-ANY accept ANY
but from AS 1 if accept community (1:3);(action xxx);
but from AS 1 if accept community (1:5); action yyy);
how do I express this in RPSL ng? Is this a typical usage of REFINE or
EXCEPT statement ?
If this is a typiical usage of EXCEPT statement it would be nice to have
some kind of appendinx for porting policies from rfc2622 to RPSLng.
Regards,
Dimitrios
