An explicit replacements defines the replacement values with the transclusion macro.

This is an example for placeholder replacements in the body of the Transclusion Macro or the Transclude Documents Macro:

product-name=projectdoc Toolbox
product-version=2.0

And this is an example of a fragment that defines the placeholders:

There current version of ${product-name} is ${product-version}.

Here is another example with the Transclusion Macro where a letter is created using placeholders.

The context replacement uses the properties defined on the page, the space the page is part of, and to spaces and pages the space or page delegates to. All properties accessible from a given point are part of the replacement context.

The Code Block Placeholder Macro uses the properties information form the page and space. The Transclusion Macro and Transclude Documents Macro can be configured to also use this feature by checking Apply Document Properties.

The impersonator feature, available since version 1.13 of the projectdoc Toolbox, allows to use property references in transclusion by replacing the owning document. Usually a page is rendered in its own context. With an impersonator the page will rendered in the context of the transcluding page.

The Transclusion Macro provides a property to define the impersonating page.
