Drop poor @attention paragraph

For one, Javadoc (unlike Doxygen) doesn't support @attention, so this caused a

> Generating workdir/CustomTarget/odk/docs/java/ref/help-doc.html...
> Note: Custom tags that could override future standard tags:  @attention. To avoid potential overrides, use at least one period character (.) in custom tag names.
> Note: Custom tags that were not seen:  @attention

warning during the build.  And for another, that paragraph was phrased in poor,
broken English and didn't add much value anyway.
