The divide sign is not a name start character in XML 1.1, nor in the
proposed 5tyh edition.

Multiply is at D7 and Divide is at F7; in 5th edition I see:
    NameStartChar	   ::=   	":" | [A-Z] | "_" | [a-z] |
	[#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] |
	[#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] |
	[#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] |
	[#xFDF0-#xFFFD] | [#x10000-#xEFFFF]

so divide and multiply are not included.

The goal is to allow name characters in names, regardess of whether
they are in the 7-bit US ASCII set of "letter" or the wider set
that people actually use.
