BEGIN WORK/COMMIT WORK/ROLLBACK WORK not being accepted in javascript functions (Java script UDF)

If I do:
curl -v -X POST http://localhost:8093/evaluator/v1/li2 -u Administrator:password  -H 'content-type: application/json' -d 'function insert1(){

var a = 1;

var query1 = SELECT 1;

var query2 = INSERT INTO test values(UUID(), {"fname": "John", "lname":"Doe"});

{color:#4472c4}}'

 

It works perfectly and I get:

• About to connect() to localhost port 8093 (#0)

•   Trying ::1...

• Connected to localhost (::1) port 8093 (#0)

• Server auth using Basic with user 'Administrator'

But if write:

curl -v -X POST http://localhost:8093/evaluator/v1/libraries/kamudf2 -u Administrator:password  -H 'content-type: application/json' -d 'function transinsert(){

var a = 1;

var query1 = BEGIN WORK;

var query2 = INSERT INTO test values(UUID(), {"fname": "John", "lname":"Doe"});

var query3 = COMMIT WORK;

Error while compiling library. Cause:

compilation failed:

Exception: SyntaxError: Unexpected identifier

Location: functions/kamudf2.js:3 

Code: var query1 = BEGIN WORK;

SyntaxError: Unexpected identifier

I think you need to add: BEGIN WORK,COMMIT WORK, ROLLBACK WORK,START TRANSACTION,SAVEPOINT as acceptable N1QL statements in your code.
