Associate tabpanel with its tab - "either by ... or by ..."

[giacomo-petri]

Suggested change
I'm not a native English speaker, but while reading the tabpanel specifications:

Authors SHOULD associate a tabpanel element with its tab, either by using the aria-controls attribute on the tab to reference the tab panel, or by using the aria-labelledby attribute on the tab panel to reference the tab.

It appears to me as if it's saying "do this OR do this," not both. Since both options are allowed and also recommended by the ARIA practices (https://www.w3.org/WAI/ARIA/apg/patterns/tabs/examples/tabs-automatic/), should we perhaps rephrase the sentence as follows:

Authors SHOULD associate a tabpanel element with its tab, by using the aria-controls attribute on the tab to reference the tab panel, and/or by using the aria-labelledby attribute on the tab panel to reference the tab.

I've noticed that "and/or" has already been used elsewhere in the document.
