Validation Conditions on "Formatted Strings"
for example "[DIRKEY!]" or "[DIRKEY /Condition * <> null]" would not allow
blank replacement, one of the major reasons why any MSI will fail.
Of course it would have been better if this was the default
but for backwards compatability this is not possible.
Exact syntax would need a lot of thought unless only supporting
non null validation in which case something like "/notnull" is more
appropriate.
