The following code used to work

define mainResponsive() {
includeHead(rendertemplate(rssLink()))
…
}

define rssLink() { } // default definition

template wikilayout(w: Wiki) {
define rssLink() { // local override
<link rel=“alternate” type=“application/rss+xml” title=“RSS” href=navigate(feed(“wiki”)) >
}
mainResponsive { … }
}

but now causes this error:
