HL7 - FN DataType inside XCN DataType?

I'm taking a look in Caristix HL7 v2.5 - Segment PV1:

And when I click PV1.9 DataType it shows DataType fields:

In XCN.2 shows FN as DataType, and FN is not just a string:

So, how can I make an example of HL7 with PV1.9 having datatype XCN that has FN inside too? I don't get it

Trying to make an example

MSH|^~\&|SA|SF||R|201802201803^450||ADT^A01^ADT_A01|2018022018035210|P|2.2||||||
EVN|A01|201802201803|||SHE7|
PV1|1|E|||||||1^Surname&Own Surname Prefix&Own Surname&Surname Prefix From Partner/Spouse&Surname From Partner/Spouse^||||

But it seems like is not right :(

After testing the message with different parsers, the way HL7 works for subcomponents are like this:

MSH|^~\&|SA|SF||R|201802201803^450||ADT^A01^ADT_A01|2018022018035210|P|2.2||||||
EVN|A01|201802201803|||SHE7|
PV1|1|E|||||||1^Surname&Own Surname Prefix&Own Surname&Surname Prefix From Partner/Spouse&Surname From Partner/Spouse^||||

Using Subcomponent separator character (&)

Then, parsed items will be like this

PV1
 |- PV1.1
 |  |- SI
 |    |- 1
 |- PV1.2
 |  |- IS
 |    |- E
 |- PV1.9
 |  |- PV1.9.1
 |    |- ST
 |      |- 1
 |  |- PV1.9.2
 |    |- XCN
 |      |- Surname
 |      |- Own Surname Prefix
 |      |- Surname Prefix From Partner/Spouse
 |      |- Surname Form Partner/Spouse

That's right.
