critical: 2 validation errors for PublicationSubset (can no longer build html using current CLI)

[Bruce Yoshiwara]

I had been able to create web, print, and print-latex versions of Kathy’s MFG (Modeling, Functions, and Graphs) using the CLI pre-version 2.0.

Evidently the CLI now requires a directory structure we have not been using. Specifically, we did not have any directory named “source”, but in the publication file included the lines
    <source>
        <directories external="../ext" generated="../gen"/>
    </source>
The ptx source files have been in a directory named "ptx".

I edited the project.ptx file that had been created with a pretext init --refresh so that project.ptx included the line
    <target name="web" format="html" source="../ptx/mfg.xml"/>
I tried a pretext build and got the error that the file source/../ptx/mfg.xml does not exist. So I tried renaming the directory from "ptx" to "source and got a new error

PreTeXt project found in `/home/byoshiwara/mfg`.
Since no target was supplied, we will use "web".

The CLI does not require a `source` directory, though that's the default.

If you can share a GitHub repo and/or your directory structure and the output of pretext support, I can help troubleshoot.

Assuming you're talking about https://github.com/byoshiwara/mfg I'll make a pull request with a 2.0-compatible project.ptx

Building now to confirm, but I believe this is what you want in project.ptx
