Summary: XmlConfig misbehaves during upgrade
Initial Comment:
This is with WiX 3.0.2813.0
Here's a component:
<Component Id="dataservices.php" Guid="MY_GUID">
<File Id="dataservices.php" ... />
<!-- register this file in my-tabs.xml on install:
<tab name="Data Services" enabled="True"
url="subdir/data-services.php" />
-->
<util:XmlConfig Id="MakeDataServicesTab"
File="[xml_dir]my-tabs.xml"
Action="create" Node="element" On="install" Sequence="1"
ElementPath="/my-tabs"
VerifyPath="/my-tabs/[EMAIL PROTECTED]'Data Services'[\]]"
Name="tab"
/>
<util:XmlConfig Id="DataServicesTabAttrName"
File="[xml_dir]my-tabs.xml"
Action="create" Node="value" On="install" Sequence="2"
ElementPath="/my-tabs/tab[\[]not(@name)[\]]"
VerifyPath="[EMAIL PROTECTED]'Data Services'[\]]"
Name="name" Value="Data Services"
/>
<util:XmlConfig Id="DataServicesTabAttrEnabled"
File="[xml_dir]my-tabs.xml"
Action="create" Node="value" On="install" Sequence="3"
ElementPath="/my-tabs/[EMAIL PROTECTED]'Data Services'[\]]"
Name="enabled" Value="True"
/>
<util:XmlConfig Id="DataServicesTabAttrUrl"
File="[xml_dir]my-tabs.xml"
Action="create" Node="value" On="install" Sequence="4"
ElementPath="/my-tabs/[EMAIL PROTECTED]'Data Services'[\]]"
Name="url" Value="subdir/data-services.php"
/>
<!-- remove the line:
<tab name="Data Services" enabled="True" url="subdir/data-services.php"
/>
-->
<util:XmlConfig Id="RemoveDataServicesTab"
File="[xml_dir]my-tabs.xml"
Action="delete" Node="element" On="uninstall" Sequence="5"
ElementPath="/my-tabs"
VerifyPath="[EMAIL PROTECTED]'Data Services'[\]] "
/>
</Component>

When I attempt a major upgrade, I get the following output in a verbose log
file:
MSI (s) (C0:88) [12:38:44:773]: Hello, I'm your 32bit Elevated custom action
server.
ExecXmlConfig: Configuring Xml File: C:\temp\htdocs\my\xml\my-tabs.xml

error: -2147020584
----------------------
It seems that:
1. On an upgrade, the VerifyPath for the "MakeDataServicesTab" element create
exists, so no no-name node is created. (Repeat THAT five times fast.)
2. The add-a-name-to-the-no-name-node step at "DataServicesTabAttrName" fails
because #1 was skipped.
I couldn't find any way to change the VerifyPath of #2 that would get around
the error message. When I look at the code in XmlConfig.cpp, it seems that the
ElementPath is checked first, and thus the VerifyPath check never comes into
play.

One more comment for clarity. This occurs when RemoveExistingProducts is
scheduled after InstallFinalize, as would seem to be appropriate. When REP
is scheduled in its other usual windows, the problem does not manifest
because the old XML changes are backed out before (re-)applying the new
ones.
