Unclear variable assignment

[mattgarrish]

In the preprocessing step, it says that package_document_as_text parameter contains the package document as a utf-8 string.

The first step then says:

LET package_document_content be textual representation of the Package document for the publication given package_document_as_text.

I don't follow what this point of this assignment is, though. It's just passing the string from one variable to another. Nothing happens until the next step when package_document_content is parsed into a dom tree.

Unless there's a purpose I'm missing, I'd suggest removing this step and just parsing the text string that's sent to the function.

This also applies to the onix techniques.
