In Go, how to parse XML with mixed elements/chardata/elements/chardata content?

Question

Let's say I have a structure, that can reference elements multiple times:

    <?xml version="1.0" encoding="UTF-8"?>
    <book category="cooking">
      <title lang="en">Everyday Italian</title>
      <author>Giada De Laurentiis</author>
      <year>2005</year>
      <price>30.00</price>
      Blah Blah Blah Bleh Blah of <year/> written by <author/>
    </book>

How can I parse this XML (or better to say, how can I describe the structure), so that I can have these internal references to it?

    type Book struct{
       t string `xml:"book>title"`
       p string `xml:"book>price"`
       y string `xml:"book>year"`
       a string `xml:"book>author"`
       blah string ???????
    }

The naïve approach (https://go.dev/play/p/JVM98pCcI0D), just to describe blah as cdata is obviously wrong, because the references <year/> and <author/> are getting lost.

What is the right way to define blah here, so that the internal structure of it, is still available after parsing?
