It is mentioned in the literals section, but not documented:

From reading forum posts I managed to figure out that
HexStrings are prefixed with an x. i.e. x"deadbeef"
Good catch! Even the grammar says nothing about what it is,
except it has HexString as a possible literal.
Can you file an issue? https://issues.dlang.org
They are deprecated:
https://dlang.org/changelog/pending.html#hexstrings
https://dlang.org/deprecate.html#Hexstring%20literals
Wow, that's... a little superfluous.
So we support this:
"\xde\xad\xbe\xef"
but not this?
x"deadbeef"
Seems like the same code you would need to parse the first is
reusable for the second, no? I don't see why this deprecation
was necessary, and now we have more library/template baggage.

For the same reason why octal literals have been deprecated years
ago:
https://dlang.org/deprecate.html#Octal%20literals
The library solution works as well and it's one of the features
that are rarely used and add up to the steep learning curve.
