Create snapshot dependency using REST

 I'm assuming a typical simple snapshot dependency scenario where build config B is snapshot-dependent on build config A, so when I execute B, A will build first while B will be on queue. Here's my call to the REST endpoint using curl

curl -v -u user:password http://localhost:81/app/rest/buildTypes/id:<id_build_B>/snapshot-dependencies --request POST --header "Content-Type:application/xml" --data @C:\snapshot-dependency.xml

This is the content of the request to post. Getting a 400 (bad request) due to this SAXParseException - premature end of file.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<snapshot-dependency type="snapshot_dependency">
     <properties count="5">
       <property name="run-build-if-dependency-failed" value="RUN_ADD_PROBLEM"/>
       <property name="run-build-if-dependency-failed-to-start" value="MAKE_FAILED_TO_START"/>
       <property name="run-build-on-the-same-agent" value="false"/>
       <property name="take-started-build-with-same-revisions" value="false"/>
       <property name="take-successful-builds-only" value="false"/>
     </properties>
     <source-buildType id="id_build_A" 
                       name="Build_A" 
                       projectName="Project_A" 
                       projectId="id_project_A" 
                       href="/app/rest/buildTypes/id:id_build_A" 
                       webUrl="http://localhost:81/viewType.html?buildTypeId=id_build_A"/>
</snapshot-dependency>

This may not be the exact xml response (It was suggested in another post) you would receive when you would get the snapshot dependencies in build B after adding the snapshot dependency to A using the call below.

curl -v -u user:password http://localhost:81/app/rest/buildTypes/id:<id_build_B>/snapshot-dependencies

I tried with that as well and it didn't work. So I basically took the root 'snapshot-dependencies' element out and also took out the ID attribute of the 'snapshot-dependency' element. The reason I did that is because I have a Python script that uses that xml request form to successfully add dependency using the Requests library. I

Please comment as to which one is the correct xml.
