Does Ace checks metadata values?

[laudrain]

Please provide the following details if possible or relevant:

[1.0.2] the version of Ace impacted by the issue (as returned by the ace -v command).
[v8.7.0] the version of Node used to run Ace (as returned by the node -v command).
[MacOS 10.3.6] your operating system and version.

• [] if the issue is a bug when running Ace: the error message as produced in the log file (you can enable debug logging with the --verbose option).
• [] if the issue is about the HTML report: the browser(s) and version(s) you used.
• [] if possible, let us know if you can share a sample input file to help us reproduce the issue.

Wrong metadata values aren't reported today by Ace.
For instance:
<meta property="schema:accessibilityFeature">401</meta>
is ok for Ace.

Could it be possible to check the values using WebSchemas/Accessibility?

In this issue, i'd like to add:

This wrong value for accessModeSufficient isn't reported by Ace.

This one is also critical.
