Fabio Arciniegas A. has released a set of stylesheets for the interpretation of XLink into HTML.
In particular, his stylesheets allow representation of one-to-many XLink arcs (for which there are no native constructs in HTML). In addition, the stylesheets also cater for other types of XLink.
Arciniegas notes that the stylesheets don't currently have "linkbase or behavioral attribute support (only
replacement for the moment)."
XLink2HTML is available from the author's web site.
