`xml2rfc` based exports fails with `src` attribute

Dear draftforge developers,

First of all thanks a lot for the development of this tool, really comprehensive and helps a lot!

Description

I am experiencing a minor issue with the embedded export tools: external files referenced via relative paths (like YANG modules in the root or in a yang/ subdirectory) are not copied over to the temp folder from where commands are executed. This causes xml2rfc to fail because it cannot resolve the relative paths inside the temporary location.

Error for reference:

Command failed: xml2rfc --allow-local-file-access --v3 --bom --id-reference-base-url="https://datatracker.ietf.org/doc/html/" --id-is-work-in-progress --text -o "/home/taarole8/git-repos/draft-netana-nmop-message-broker-bmp-telemetry-message/draft-netana-nmop-message-broker-bmp-telemetry-message-00.txt" "/tmp/draftforge-zGqCcS/1769759774921.xml" /tmp/draftforge-zGqCcS/1769759774921.xml(13): Warning: Setting consensus="true" for IETF STD document (this is not the schema default, but is the only value permitted for this type of document) /tmp/draftforge-zGqCcS/1769759774921.xml(64): Warning: The document date (2026-01-26) is more than 3 days away from today's date /tmp/draftforge-zGqCcS/1769759774921.xml(2360): Error: Expected a file at '/tmp/draftforge-zGqCcS/ietf-bmp-bgp-rib-entry@2026-01-26.yang', but no such file exists Not creating output file due to errors (see above) Unable to complete processing /tmp/draftforge-zGqCcS/1769759774921.xml

Running xml2rfc from the terminal works.

Is there a workaround to force other files to be copied to the temp dir?

Cheers,
Leonardo
