Hi Athos,

Thank you for working on this RFP, and for doing all the work involved
with reintroduction the package.

I'm CCing the debian-legal team who I hope will be able to help with
the stylesheet question and related issues; I've given it my
best-effort, but would appreciate someone else's perspective

My reply, in context, follow inline:

Do you mean the PHP-3.0[-only] issue:

  https://lintian.debian.org/tags/license-problem-php-license

which appears to be the same as the PHP-3.1[-or-greater?] issue?

  https://ftp-master.debian.org/php-license.html

Is the problem you're referring appears to be that this license places
limitations on the use of the term "PHP"?  Were this limitation on
endeavour, it would be non-DFSG, but honestly I'm a bit surprised that
php8.1 is in Debian main...eg: that it's DFSG-free.  I'm also not sure
why the Apache license isn't problematic for this same reason.

At any rate, as far as I can tell this is something for the ftpmasters
to worry about, so long as you follow the instructions at the above two
links as well as consulting the PHP package for examples.  Ie this means
is that the debian/ subdir must have a more permissive license than the
PHP one (eg: Expat).

Oh my!  Yes, after reading that issue (quoted below):

The copyright text on the PHP website is

    Except as otherwise indicated elsewhere on this Site, you are free
    to view, download and print the documents and information available
    on this Site subject to the following conditions:

      * You may not remove any copyright or other proprietary notices contained
        in the documents and information on this Site.

      * The rights granted to you constitute a license and not a
        transfer of title.

      * The rights specified above to view, download and print the
        documents and information available on this Site are not
        applicable to the graphical elements, design or layout of this
        Site. These elements of the Site are protected by trade dress
        and other laws and may not be copied or imitated in whole or in
        part.
    (https://www.php.net/copyright)

To me it sounds like 1. No rights to redistribute the website (in whole
or in part) are granted, except where the part is a separate project
with its own license (php-docs).  2. No one has a license to view,
download, or print the stylesheets.

Were the second claim to be maintained, a consequence of this would
seems to be that only the copyright holder[s] could build the
unpatched documentation without committing copyright infringement.

Good point; however, the Apache license allows relicensing (so long as
various conditions are met).  Were the PHP project to not do this, they
would be in breach of the Apaache license, and we still wouldn't be able
to redistribute.

Given the copyright notice published to the PHP website, I think you're
right about how the only workaround is to replace their stylesheets!
Please note that network access is blocked during the builds of all
Debian packages (packages in non-free are not part of Debian).

I also wonder if the future php-docs package could download the
stylesheets and build the docs on the end user's machine as part of
package configuration (analogous to how ttf-mscorefonts-installer
works); however, I'm not sure if that's legally permissible in this
case.

Please keep me in CC.

Nicholas
