Android: How to inject a <string> element into another <string> element in XML?

I would like to know whether there is a way to insert/inject a <string> element defined in an XML file into another <string> element, doing that just with XML.

For example I could have:

<string name="author">Francesco</string>`

and I am looking for something like:

<string name="about_application">Author: @string/author</string>`

so that getString(R.string.about_application) would result in "Author: Francesco".

I know that I could combine the two elements in Java code using String.format(string, formatArgs)like for example:

<string name="author">Francesco</string>
<string name="about_application">Author: %1$s</string>`

and then in code use

String.format(getString(R.string.about_application), getString(R.string.author))

but I would like to do it in XML directly.

Can anyone suggest me a way to do it?
