Label "for" attribute is wrongly documented as required [SPR-14287]

[spring-projects-issues]

Paul Benedict opened SPR-14287 and commented

JavaDoc says "for" is required for the Label tag:
https://docs.spring.io/spring/docs/4.3.0.RC2/javadoc-api/org/springframework/web/servlet/tags/form/LabelTag.html

The TLD doc says the tag has no required attributes:
http://docs.spring.io/spring/docs/4.3.0.RC2/spring-framework-reference/html/spring-form-tld.html#spring-form.tld.label
