[x3d-public] Additional "]>" characters rendered in X3D 4.0 HTML output, due to non-standard DOCTYPE

Thu Jan 28 14:43:15 PST 2021

The latest X3D 4.0 drafts render with an additional "]>" characters at
the beginning of every page. I attach screenshots.

This can be seen on any page, e.g. visit
https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-WD3/
. In Firefox and in Google Chrome.

The effect is even weirder if you open the frame version through the
main page. Both frames start with "]>".

Running "ant" in the repo it reports for all HTMLs:

    sound.html: Doctype given is "&#x2014;"

... which is also a symptom of the problem.

Looking at HTML source code, every HTML starts with this non-standard
DOCTYPE line:

"""
<!DOCTYPE html [ <!ENTITY mdash "&#x2014;"> <!ENTITY nbsp " ">
<!ENTITY infin "∞"> <!ENTITY minus "−"> <!ENTITY pi
"π"> <!ENTITY plusmn "±"> <!ENTITY times "×"> <!ENTITY
le "≤"> <!ENTITY ge "≥"> <!ENTITY copy "©"> ]>
"""

So... neither Tidy, nor Firefox, nor Google Chrome understand this
non-standard DOCTYPE in a way that was probably intended.

Can we change the DOCTYPE to be more standard? Preferably just
simplest """<!DOCTYPE html>""" as you can see on all other web pages
:)
