glossary: update attribute

[PassionPenguin]

Description

xml attribute behaviour fixes

Motivation

1. in most compiler/parser, xml attribute with no = and "value" is not allowed and will throw an error of "the spec mandates value for attribute #attr"
2. in w3c recommendation of XML, attribute is defined as attr eq value

Additional details

1. w3c https://www.w3.org/TR/xml#sec-starttags
2. xml validator (searched google and chose first five parser, all throw the same error)

tested that will throw an error:

<tag id />

@PassionPenguin nice work! I had a few language suggestions for you, but nothing major.

[chrisdavidmills]

Surely it is still equivalent to this as well? Include this one as well as the other one?

[PassionPenguin]

i have mixed with the original document (line 13’s removal or the attribute's name in XML.). this is indeed equivalence of html attr=“attr”.

(i’ve checked html spec from + to 5, and in all specs, boolean attribute is true only requires the attribute to exists)

[chrisdavidmills]

That is super interesting — I thought it would have to be required="required" to work, but I tested it and you are correct — it can indeed be required="anything".

Today I learned something ;-)
