For highlighting of non-typeable atoms in JCP, a constant is needed. This is commit 856197c02328369333f0442d664a02f33a7175bf in the ebi git repository. If you think there is a better solution, tell me.
Sorry, the commit is actually 38cddc0c2114487c013dce76354eba6d1b81f4c1
And ebi git is at http://www.ebi.ac.uk/steinbeck-srv/git/cdk/
Patch looks ok. Applied to CDK master and pushed
