EPUB missing image warning

[ascholerChemeketa]

Currently, if the packaging_tree that is built for an EPUB ends up with images that are missing a sourcename it results in a broken build. This is happening when I try to build the sample-book with -f epub-svg.

This produces warnings for each image that does not end up with the right information but allows the build to continue.

results in a broken build

In what way? I get an EPUB that is readable by calibre and epubcheck (though the former is not always pretty and the latter has errors).

It appears to me that @sourcename really shouldn't be empty. Might it be better to get to the root of the problem?

It looks like the cause of the images missing expected attributes are the ones injected into the source tree in the representations pass:

pretext/xsl/pretext-assembly.xsl

Line 2769 in 8a0b43c

Should I turn this into an issue based on those images not meshing well with the packaging-info template?

I was suspicious of that, and went looking, and I think I got distracted by some other rabbit holes...

Yes, please! Don't get rid of this - the warning will be good for when we mess this up again. ;-)
