If the control implementation statement includes a reference to a control, say IA-5, make that a hyperlink to the control IA-5.
Conversely (and this may require a sqlite database): under every displayed control implementation statement, include a list of the controls that link to it.
The regex to search for control identifiers in text might be something like \b[A-Z][A-Z]-\d\d?\b (untested).
