You can try:
 [value name="dynamic_var-[[value dynamic_flag]]" set="some text"]
That's maybe a minivend 2ism  ;^)  At any rate, minivend is
almost certinly not interpolating [value dynamic_flag] **before**
the other [values].  I'd do it in perl, maybe someone else can
point out how in tags.

Minivend tags are not proceedural.
