Hi Giuseppe, The reason is the specification: entities in comments are adopted without change (i.e. in their literal representation) [1]. The following example expression will be successfully evaluated: <!--{xyz;-->/data() Cheers, Christian [1] https://www.w3.org/TR/xquery-31/#doc-xquery31-DirCommentContents On Tue, Nov 17, 2020 at 6:18 PM Giuseppe G.

Hi,

<!----->/data() is printed as - , while "-” as - (even if both are xs:string): is there a reason? In any case, is there a function to convert <!-----> into - ? Thanks.

Best, Giuseppe
