Sigil 1.9.30 and unsupported media-type
Running Sigil 1.9.30 on Windows 10.
I recently got hold of an Epub that has Sigil, upon loading this epub, complaining about an unsupported media-type "Application/XML" for a file in the OPF. Sigil replaces this with a temporary media-type, but strongly advises to correct the OPF.
Surely "Application/XML" is supported? Or am I missing something?
TIA for any info.
