IIS 10 support - conditional IIS version detection

[wixbot]

I have a text control with the following condition:

<Control Type="Text" Id="noSupportedIISInfo" Width="280" Height="42" X="30" Y="120" Text="Because the installed version of IIS is not supported, installation is available only as a Windows Service." Hidden="yes">
      <Condition Action="show"><![CDATA[IISMAJORVERSION AND IISMAJORVERSION <= "#5"]]></Condition>
  </Control>

The problem is that the above condition is true on Windows 10 where IIS 10 is installed. What can I see from the log is:

PROPERTY CHANGE: Adding IISMAJORVERSION property. Its value is '#10'.

so it seems that

    "#10" <= "#5" 

returns true while I would expect the result to be false because the values should be considered as numbers not strings. Would be great to have it solved in WiX - support for next IIS versions.

That's how MSI works: It has only string comparisons and '1' < '5'. I opened a new feature request to simplify: http://wixtoolset.org/issues/4851/
