This feature is like a regular expression which prefixes local Anchors 
after the HTML is generated by TYPO3 imho. We had several problems with 
that feature also. Maybe you can check your output without the 
prefixLocalAnchors and ask the W3C Validator if everything is fine - 
maybe the regex has problems due to untypical HTML output.
