  Sorry if I'm being a pain. However, if you know that mention does not occur in the Jewish liturgy, then it's a knowable quantity, and reliable sources can say so. Now, I know that sources are not often going to address a silence, although the wranglings that some do over this issue might spark responses. So I would suggest that we wait a long time for a source to be found before removing the paragraph. The search could be prolonged. On the other hand, just how long is the liturgy you're talking about? The Seder meal only? If so, that's not so long that it can't be reviewed in toto, and the liturgy itself becomes the source. What could be more reliable than that?
