<modifySql context="ctx_name"> with append is not working

I’m trying to use contexts inside modifySql for createTable to append “partition by”. But the contexts are not being considered and the sql is not being appended at the end.


                                    ....             ....                              
Here I'm passing context value through "liquibase.properties" as "contexts=usePartition", still it is not appending the append value.

is it the rightway of passing contexts for modifySql?

liquibase version: 2.0 RC-2 (Build - 143)
database: Sybase 15.0.3 (Adaptive Server Enterprise)

I’ll take a look.  I created an issue to track it: http://liquibase.jira.com/browse/CORE-563
