Currently, references from the Web Profile and associated Test Guide to the WSTG are unversioned, which makes such references ambiguous. I believe the current version of WSTG at time of publication of the Web Profile and Test Guide was 4.2, however there is at least one reference to a WSTG test that does not seem to exist in version 4.2 (WSTG-ATHZ-05).
We should update the documents with versioned references to resolve this ambiguity.
