The link code is in fact still present; [[page#anchor]] and [[#localanchor]] will produce a link exactly as expected. My original syntax for placing the anchor itself as [[##anchor]], but other suggestions are welcome.
For link, [[page#anchor]] and [[#localanchor]] seem to be natural because I proposed the same syntax without knowing of your proposition ;o) For anchor creation syntax, I though about [[anchor:MyAnchorName]]. Where "anchor" will be translate in the local language file to be more comprehensible. One more time I think it's really sad to deprive ourself of using a good feature just because of the fear that someone use it in "bad" way.

PS : other proposition : #ANCHOR anchorname (like #REDIRECT article)
