How to use variables in a _service file

[jmandawg]

Hi all,

I search through the docs but could not find any info on this.

Is it possible to use variables (possible from some sourced file) in the _service file?

for example:

<services>¬
  <service name="download_url">¬
     <param name="host">commondatastorage.googleapis.com</param>¬
     <param name="protocol">https</param>¬
     <param name="path">/chromium-browser-official/chromium-${MY_CURRENT_VER}.tar.xz</param>
   </service>¬
</services>

Where MY_CURRENT_VER is a variable stored in another file?
