I open an SCL file containing several IEDs. I'd like to remove all IEDs except for a specific selection of IEDs.
[More information on the background of my task: (*)]
! Please find the used SCL file attached to this issue:
2026_DSS_SysCon_DIGSI_Q03.zip
The validator is fine with the imported SCL file:
Now, I select all IEDs except for the following:
- AA1E1Q03BPCU
- AA1E1Q03SCU
- AA1E1Q03MU
- AA1E1Q09BCU
- AA1E1Q09SCU
After removing the selected IEDs, schema validation throws many issues:

The reason for each of them is "duplicate lines", for example:

For now, my workaround is to simply delete the whole Substation section (where all the schema issues come from).
(*) To give some background about the reasons for this task: I have finished the configuration of all IEDs in the proprietary ICTs. However, I want to do some minor changes. Therefore, I need to import my SCD file to Siemens DIGSI SCT in order to update a specific selection of IEDs. However, this ICT doesn't provide the possibility to select which IEDs I actually want to update - it simply updates all IEDs available in the imported SCL file. So, in order to not change anything in the IEDs that I do not want to update in DIGSI, I want to delete them first using OpenSCD, before importing that file in the DISGI SCT...
