Just to check that by "valid potential QName" you mean a string that is in the lexical space of xs:QName and will therefore constitute a valid QName provided the prefix is in scope?
($x castable as xs:QName) will not work because (a) it also tests whether the prefix is in scope, and (b) to avoid the issues of it therefore being context-sensitive, the W3C spec says this is only allowed if the argument ($x) is a string literal.
So you do need to use the regex approach.

Subject: [xsl] are all strings in a sequence valid potential QNames
As for example, in determining element and/or attribute names from the first line of a csv file, as well as other similar cases, with xslt2.0 (e.g. without "map", "try", and schema), what is the best way to check (e.g. true/false) that 1. a string is a valid potential QName (e.g. match + what regex?, or other option) 2. all strings in a sequence are valid potential QNames
Thank you, ac
