0021 /** Mike Case 2007x12x18
0022  * Important note:  The removal of throwing and catchine a DDException is
0023  * based more on "what is" rather than the ideal.  We have managed to force
0024  * users to put all SpecPar types and filters at the end of the set of XML
0025  * files.  Therefore a DDValue of the XML syntax "[myvar]-2*[myothervar]"
0026  * will have a correctly evaluated number and valid doubles by the time this
0027  * code is ever run.  What will happen now, is possibly a crash if someone mis-
0028  * identifies their variables to the DD.  I use edm::LogWarning to attempt to catch
0029  * one type of such problems.
