The display hint shows the value is 11 chars long. The minLength and maxLength fields are both set to "8". There really should be two min and max length restrictions (8 and 11). What happens if there are more?

I cannot reproduce this bug neither in version 0.4.1 nor in version 0.4.2-pre1 (current CVS). The correct behavior should be not to generate min/maxLength facets. The pattern already includes the length information. Actually, it is composed of two patterns, one describing the string with a length of 8 and another pattern describing the string with a length of 11.

If there were more than two length restrictions the generated pattern would be composed of more than two (sub-)patterns.
