XSLPattern was the "draft standard" for XPath who's largest implementation was released as part of IE (either 5 or 6, I'd have to go look it up). By the time standardization of XPath 1.0 was complete (including separating the XSLT and XPath languages, which were not separate at the time of the draft), several changes had occurred altering the syntax on many (but not all) queries. The only processor still in production implementing the obsolete draft is MSXML3, which XmlFile and XmlConfig use.
Unfortunately when XmlFile was added to WiX, that history must not have been known/understood or I believe they would have simply hardcoded the pattern to use. MSXML3 couldn't default to the current standard because of legacy code in use. All "newer" MSXML releases use XPath exclusively, as does the .NET implementation. I wrote a little tool to "MSI-format-ify" strings that I can use to "convert" my tested XPath into what I need to place into my WiX. One of these years I'll clean up that code and contribute it to the OSS universe...

Subject: Re: [WiX-users] XmlFile element issues - any XPath experts out there? Thanks, although I have it working now without setting the SelectionLanguage, I did try that out when debugging. I assume they are very similar if my XPath pattern match works as expected even when parsed as XSLPattern.
