jr:constraintMsg description references jr:requiredMsg="message" example

under https://opendatakit.github.io/xforms-spec/#bind-attributes:

> jr:constraintMsg | Specifies the custom message to be displayed when the constraint is violated. Value can be string literal (**jr:requiredMsg**="message") or a translation function call (**jr:requiredMsg**="jr:itext('id')").

'nuf said :-)

Open the bind-attributes section of the XForms specification at the linked URL and review the jr:constraintMsg example. Check the attribute names in the surrounding text, correct the inconsistent example, and verify that the description and example refer to the same attribute.
