Qualifier Icons
Schema elements can have additional icons that specify qualifications. The qualifier icons have different meanings depending upon where they appear. For example, a question mark icon signifies an element is optional in the Scope Variables schema or in a hint in the Function panel. However, in an XSLT statement, the question mark signifies the statement is "collapsed" and an implicit "if" statement is set, but not displayed in the Function panel.
The following table describes the additional qualifiers that appear next to the name of schema items.

Content tab of the Edit Statement dialog.
