I am trying to add <a href="tel:+1234567890">1234567890</a> in RTE
RTE is not able to render the same HTML as added in RTE.
In xssProtection config
To resolve this I have added
<regexp name="telListing" value="tel:\+[0-9]+"/>
<attribute name="href">
<regexp-list>
<regexp name="telListing"/>
</regexp-list>
</attribute>
it is accepting <a href="tel:1234567890">1234567890</a>
but not <a href="tel:+1234567890"> 1234567890</a>
adding plus is an issue
