What meaning does "hexadecimal" add in "any hexadecimal character"  Is it any
different from "any character"?  If not, "hexadecimal" is a noise word.

I'm similarly perplexed by IBM's frequent usage, as in:
    
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.ieaa200/ENQ_Description.htm
    ... The name can contain any valid hexadecimal character. ...

I visualize a Venn diagram:  https://en.wikipedia.org/wiki/Venn_diagram
where invalid hexadecimal characters and valid non-hexadecimal characters
are prohibited.

I'm tempted to submit an RCF requesting a clarification.
