The following bugs are ones I personally identified and submitted through Oracle Support. If you need any more clarification or help on these, feel free to ask:
Bug #7284766 (Content Server) - DATA SERIALIZER DOESN'T PROCESS CHECKBOX HCSF CORRECTLY FOR SUBMIT_HTML_FORM
Summary: If you use the SUBMIT_HTML_FORM idcservice, checkboxes with the same name/id will not be handled and processed correctly. Also, the resulting "xml data island" of the form that is checked in will not store the checkbox data.
Oracle Response: "Yes the issue is fixed in 11g but development cannot back port it to 10gR3 because that requires a significant enough change that it would require a full regression QA cycle of the 10gR3 media and no such regression QA cycle is planned at this time. Regression tests are likely to only occur if critical BUGs are found. If some really large 10gR3 BUGs were found that had to be fixed (an event that is currently considered unlikely), then it is possible that this fix could be rolled in with the fixes to the larger BUGs before the regression test would be performed."
