itcFirst (7 bits): If fCol is zero, this value MUST be ignored. Otherwise, this value is an unsigned integer specifying the zero-based index of the table column that is the start of the table column range associated with the bookmark described by this BKC. See itcLim for additional constraints on the value of itcFirst.
A - fPub (1 bit): This value MUST be 0, and MUST be ignored.
itcLim (6 bits): If fCol is zero, this value MUST be ignored. Otherwise, this value is an unsigned integer specifying the zero-based index of the first column beyond the end of the table column range associated with the bookmark described by this BKC.

For all bookmark types, itcFirst MUST be less than itcLim if fCol is not zero.
For range-level protection bookmarks, itcLim MUST be exactly 1 greater than itcFirst if fCol is not zero.
B - fNative (1 bit): A bit flag that specifies whether an application is expected to include the bookmark described by this BKC when saving its file as Rich Text Format (RTF), HTML, or XML. If fNative is zero, the bookmark is no longer needed and is a disposable item that was generated by the application to act as a temporary placeholder at run time. The bookmark is not expected to be included if the file is saved as RTF, HTML, or XML.
C - fCol (1 bit): For structured document tag bookmarks and annotation bookmarks, fCol MUST be zero. Otherwise, if the lowest table depth within the span of text defined by the CPs of a bookmark is greater than zero, and the span of text defined by the CPs of that bookmark contains a table cell mark from that table and nothing outside that table, then the fCol member of the bookmarkâs (1) BKC MUST be 1. Otherwise, it MUST be zero. If the fCol member of the BKC of a range-level protection bookmark is set to 1, the span of text that is defined by the CPs of that bookmark MUST NOT include more than one table terminating paragraph mark. Further constraints upon the span of text defined by the CPs of a bookmark can be found in section Plcfbkf.
