Actually this construct is not valid. Anchor names as defined by the id
and name attribute in this example must identify a unique element, hence
if you want to use both, the id and the name attribute, you must use
them for the same element (i.e., <a> in this example). The W3C HTML
Validator is unable to detect this error, but e.g. http://tidy.sf.net/
will complain:

  line 1 column 17 - Warning: <a> Anchor "topic5" already defined
