Hi Lada,
Look at below examples,
module ietf-test {
namespace "urn:ietf:params:xml:ns:yang:ietf-test";
prefix itest;
import ietf-interfaces {
prefix if;
}
augment "/if:interfaces/if:interface"{
list A{
key "a";
leaf a{
type string;
}
}
}
grouping B{
leaf b{
type leafref{
path "/if:interfaces/if:interface/A/a";
}
}
}
}
module ietf-foo {
namespace "urn:ietf:params:xml:ns:yang:ietf-foo";
prefix foo;
import ietf-test{
prefix itest;
}
container C{
uses itest:B;
}
}
when I run the "ietf-foo" module, the "current module's prefix" is "foo" and I
receive a error report： .\ietf-test.yang:32: error: ietf-foo:A in the path for
b at ietf-foo.yang:23 (at
.\ietf-test.yang:30) is not found.
I believe it means, the path "/if:interfaces/if:interface/A/a" in module
"ietf-foo" is equal to "/if:interfaces/if:interface/foo:A/foo:a"

No, it is not, because if the expression appears inside a grouping, then the
next sentence of the same bullet says "that namespace is affected by where the
grouping is used".
