[wix-users] Extensibility

[Christopher Painter]

You said you didn't want it to influence the MSI.   To me this sounds like using a preprocessor XPI  as a meta tag.  Something like

<?define MyTag="foo"?>    
<Feature.....>

You could do an XML query on your feature and then look for the XPI above it to get your additional meta for that feature.

To me a custom attribute on the Feature element would manfiest as a column in the feature table of the MSI.  A custom child element would manifest as a table with a join back to the Feature table.     My suggestion above would merely be source code meta and not compiled into the MSI at all.

Yes, I „need” it to function as a tag.
Have a couple of scripts going over sources, fragments, includes and it
would be nice if those scripts could find certain information in the XML
that is being loaded/parsed anyway.
Far easier to execute an extra x-query than to parse external databases
that must be correlated with elements in XML files.
Plus it would be a good exercise to create such an extension.
