Repro Steps

Build a Merge Module with the following WiX source code:

<Module Id="FileSearch" Language="1033" Version="1.0.0.0"
          Guid="{110CF125-7A17-41F1-9C16-DDDAE0A1B03A}" InstallerVersion="500">
        <SummaryInformation Manufacturer="Licence Owner" />
    <Property Id="FILEFOUND" Secure="yes">
      <DirectorySearch Id="Windows" Path="[WindowsFolder]" >
        <FileSearch Id="MyFile_ini" Name="MyFile.ini" />
      </DirectorySearch>
    </Property>
</Module>

Actual Result

Error message:

WIX0001 System.InvalidOperationException: The value '' is not a legal identifier and therefore cannot be modularized. C:\MySourceCodePath\Installation\MergeModules\FileSearch\wix.exe 1

Expected Result

I expect the code to compile, resulting in a Merge Module with entries in the AppSearch, Signature, and DrLocator tables.

In WiX 3, this code compiled.
