A wrapper custom action is a Type 1 CA whose puprose is to implement the
encapsulation / adapter pattern for another DLL whose interface / function
definition is incompatible with MSI.
The wrapper CA basically does the approriate MsiGetProperty and
MsiSetProperty calls along with MsiProcessMessage, LoadLibrary and error
handling to map the correct properties to the function arguments of the method
being wrapped.
Btw- InstallShield actually has what they call the `standard DLL` CA type
that is basically a table data driven adapter pattern. This has been useful in
the past but I don't think WiX has anything like this built into it.
