How to add a export to the WEXP export server queue with DXL?

Hi everyone,
 
I'm a beginner with DXL codes. I'm currently building a little script that could launch some WEXP exports without opening any GUI or other prompts. To do this, I configured a WEXP Export server and I plan to add documents in the spooler with DXL code.
 
I'm looking for a DXL command which could almost do the same job as the WEXP_userExportCode() except that it should send the export request to the spool of the WEXP export server. In other words, how could I do the same thing as if I click the "Export in batch" button in the WEXP GUI but via a DXL script?
 
I've already looked for a list of WEXP commands and I didn't find anything that could help. Since the RMF sources are encrypted, it's quite difficult to find which functions we can use. I'm also wondering if I can do something like eval_("#include </addins/irdrmfao/…/.inc >") with the .inc file that send the export to the spool, this after having configured the global parameters for WEXP in batch mode (WEXP_exportName, WEXP_exportView, …) . However, I've no idea of which file is doing this job…
 
I would be infinitely grateful if somebody could even enlighten me with this issue.
 
Thank you in advance
