The trait SimpleSAML\XML\TypedTextContentTrait requires some properties which are not provided by SimpleSAML\SAML2\XML\md\EmailAddress: $localName, $namespaceURI

    /** @var string */
    public const TEXTCONTENT_TYPE = EmailAddressValue::class;

    public function getContent(): string
    {
        return preg_filter('/^/', 'mailto:', $this->content->getValue());

The expression return preg_filter('/^/', 'mailto:', $this->content->getValue()) could return the type array|null which is incompatible with the type-hinted return string. Consider adding an additional type-check to rule them out.
