Yes, but it also allows all the digits for the first character.  In the XML
and Namespaces Recs, the first character is different from the rest and does
not allow them.  Digits are defined as

 Digit    ::=    [#x0030-#x0039] | [#x0660-#x0669] | [#x06F0-#x06F9] |
[#x0966-#x096F] | [#x09E6-#x09EF] | [#x0A66-#x0A6F] | [#x0AE6-#x0AEF] |
[#x0B66-#x0B6F] | [#x0BE7-#x0BEF] | [#x0C66-#x0C6F] | [#x0CE6-#x0CEF] |
[#x0D66-#x0D6F] | [#x0E50-#x0E59] | [#x0ED0-#x0ED9] | [#x0F20-#x0F29]
