Several times in a project, there is a requirement that the OOTB link checking in AEM needs to be disabled for specific links.
x-cq-linkchecker="valid" : This will make the linkchecker mark the link as valid.
x-cq-linkchecker="skip" : This will make the linkchecker skip the link.
These tags should need to be added on the <a> tag directly, for example:
<a href="xxx" x-cq-linkchecker="skip">Link</a>
