XML Schema Part 2: Datatypes

In Appendix F, Regular Expressions, of XML Schema Part 2: Datatypes, the IsBlock
production [38] only allows letters, digits and the hyphen for the block name,
but the block name "Latin-1Supplement" contains a digit.  The production should
allow at least the digit 1 to accommodate this block name or (preferably, in my
opinion) allow all decimal digits 0-9.
