Title: don't make the optionality of the channel element stand out in ctkCmdLineModule.xsd

Currently, the channel element stands out, because its optionality is formulated differently, which confuses people like me who're not too proficient with XSD.
(The other optional elements do not have maxOccurs=1 or an extra comment.)
