When using identical headings (e.g., derived from some kind of template), the automatically generated anchors will be non-unique.
A prominent example is the TWikiReleaseNotes04x02 topic as shipped with TWiki 4.2.1 which contains redundant
Fixes and
Enhancements sections (for 4.2.0 and 4.2.1, respectively). Using Firefox3, it is not possible to select the newer subsections from the TOC (NB the browser behaviour in this case is unspecified).

As a work around you can put a unique html comment after identical head lines. The URL generated by the TOC includes these characters
---++ Some header<!-- number1 -->
---++ Some header<!-- number2 -->
Trying it for real
Some header
Some header
Setting to no action since we have Item1607. I changed 1607 from enhancement to Normal. it is a bug - not an enhancement.
