OpenSP: Value of attribute ... must be a single token
This attribute can not take a space-separated list of words as a value, but only one word ("token"). This may also be caused by the use of a space for the value of an attribute which does not permit it.
|<a name = "two words">|
|<a name = "two_words">|
Use camelCase or underscores to join words.
