Resolution

Reword in terms of regular expressions:
[Definition:]  pattern is a constraint on the ·value space· of a datatype
which is achieved by constraining the ·lexical space· to ·literals· which match
each member of a set of regular expressions.

And add a note in the first paragraph:
"Note:  An XML <restriction> containing more than one <pattern> element gives
rise to a single regular expression in the set; this regular expression is an
"or" of the regular expressions that are the content of the <pattern>
elements."
