syntax errors when specifying px rules with exec transitions that have '.' in the name

[Jamie Strandboge]

$ echo 'profile test { /foo/** px -> snap.foo.bar//&baz }' | apparmor_parser -QTK
...
AppArmor parser error, in stdin line 1: Found unexpected character: '.'

$ echo 'profile test { /foo/** px -> baz//&snap.foo.bar }' | apparmor_parser -QTK
AppArmor parser error, in stdin line 1: syntax error, unexpected TOK_ID, expecting TOK_END_OF_RULE

I found myself wanting to do this again and tried this:

@{OTHER_PROFILE}="snap.foo.other"
profile snap.foo.bar {
  /some/path Px -> @{OTHER_PROFILE},
}

This indirection allows the profile to compile but unfortunately can't transition to it:
