Usage of "passthrough" token in DITAVAL documents

The DITA Technical Committee wants to know if folks are using the “passthrough” token for the @action attribute on <prop> elements in a DITAVAL document. We’re not considering removing it, but just want to know whether it is being used.

The @action attribute on the <prop> element is where one specifies what should happen to the content. It takes the following values: exclude, flag, include, and passthrough.

Specifying action="" means that filtering and flagging is deferred. Metadata is retained in the output (if supported by the output format), so that filtering and flagging is possible at delivery time. (Obviously, this depends on support from both the DITA processor and whatever delivery platform is used.)

Example:

The following code sample shows a DITAVAL document. It indicates to processors that content tagged with product=”premium” should be excluded, and that the filtering and flagging should be deferred for included content tagged with the @otherprops attribute.

<?xml version="1.0" encoding="UTF-8"?>

<val>

<prop action="" att="otherprops"/>

</val>

Best,
