It's only partial solution. In this manner I can not constraint length of
substrings enclosed in string.
I dont speak english very good, but as i undestand in XML Schama 2:
S{n,m} ..... All sequences of at least n, and at most m,
"at most m" schould mean "NOT more then m, inclusiv m"
By the way, such a possibility "more than m ist valid too" is senseless,
because if more than m ist valid, so why to specyfy m?
For example, XML Spy 3.5 and 4.0 doesn't accept strings longer then m.
XSV doesn't validate patterns at all.
