In the following declaration, I create two connection managers, one for a file based connection manager and one for a SQL connection to my named instance.

<Biml xmlns="http://schemas.varigence.com/biml.xsd">
<Connections>
<FileConnection Name="FCChild" FilePath="c:\Users\bfellows\documents\visual studio 2012\Projects\SSISPOC\PackageDeploymentModel\Child.dtsx"></FileConnection>
<OleDbConnection Name="OLEChild" ConnectionString="Data Source=localhost\dev2012;Initial Catalog=tempdb;Provider=SQLNCLI10.1;Integrated Security=SSPI;"></OleDbConnection>
</Connections>
<Packages>
<Package Name="Child"
ConstraintMode="Linear"

</Package>
<Package Name="Parent"
ConstraintMode="Linear">
<Tasks>
<ExecutePackage Name="EPT File Child">
<File ConnectionName="FCChild"></File>
</ExecutePackage>
<ExecutePackage Name="EPT SS Child">
<SqlServer ConnectionName="OLEChild" PackagePath="\Child"></SqlServer>
</ExecutePackage>
</Tasks>
</Package>
</Packages>
</Biml>
The resulting Execute Package Task for the SQL Server appears as
