Actually Bob Arnson was right.
I have the following code works:
1) In Bundle.wxs:
<Variable Name="db_name" Value="old_db_name"/>
<Chain>
<MsiPackage Id=SomeMsiId SourceFile="some.msi">
<MsiProperty Name="DB_NAME" Value="db_name"/>
</MsiPackage>
</Chain>
2) In BA managed code:
MyBootstrapperApplication.Bootstrapper.Engine.StringVariables["db_name"] =
"new_db_name";
Now some.msi will be launched something like this: msiexec.msi /I some.msi
DB_NAME="new_db_name"
The tip is: Value in MsiProperty values EXPRESSION that can contains
references to Burn variables (like db_name in my example)

You can implement the bootstrapper to launch the .msi package using
the command line msiexec /I {package.msi} PROPERTY1=value1 PROPERTY2=value2.
However, if you do this, you have to manually manage all specific
scenarios (upgrade, uninstall, patch, etc).
A better solution is to encapsulate the code to retrieve specific
information in custom actions and drop the bootstrapper altogether.
