+ String containing markup for the label. It may contain markup tags
+ described above and newline characters but currently only wxGTK and
+ wxOSX support multiline labels with markup, the generic
+ implementation (also used in wxMSW) only handles single line markup
+ labels. Notice that the string must be well-formed (e.g. all tags
+ must be correctly closed) and won't be shown at all otherwise.
