I disagree with that: XSLT is both capable and suitable for
calculating a simple discount.

The people who designed XSLT intended it to be used for either
purpose.  That is why the top level element can be either
xsl:stylesheet (for presentation) or xsl:transform (for logic).
(Using one or the other has no practical significance, it is just a
statement of intent).

As others have already said, it is of course good practice to keep the
two separate.  The original problem arises from poor use of language
rather than poor choice of language.
