Comment (by Baptiste Mispelon):
Using the table you linked to, I get the same list of 24 attributes. The
table is labelled as "non-normative" but I think it would be good enough
for this usecase.
I tried various other ways of extracting the list from the spec but this
table seems like the best method. It's missing `truespeed` which is a
boolean attribute for the `<marquee>` tag (which is deprecated) so I think
it's acceptable.
For reference, here's the script I used to get the list (piped to `sort
-u` to remove duplicates):
{{{#!py
from urllib.request import urlopen
from lxml import html # needs to be pip-installed (`pip install lxml`)
if __name__ == '__main__':
# The spec is an 11Mb file, downloading it takes a while
response = urlopen('https://html.spec.whatwg.org')
tree = html.parse(response)
for i, row in
enumerate(tree.xpath('.//table[@id="attributes-1"]/tbody/tr')):
assert len(row) == 4, f"Expected 4 columns on row {i}, got
{len(rows)}"
attr, elements, description, value = (node.text_content().strip()
for node in row)
if value == "Boolean attribute":
print(attr)
}}}
