/**
* PropertyEditor for TransactionAttribute objects. Takes Strings of form
* PROPAGATION_NAME,ISOLATION_NAME,readOnly,timeout_NNNN,+Exception1,-Exception2
*
where only propagation code is required. For example:
*
PROPAGATION_MANDATORY,ISOLATION_DEFAULT
*
*
The tokens can be in any order. Propagation and isolation codes
* must use the names of the constants in the TransactionDefinition class. Timeout values
* are in seconds. If no timeout is specified, the transaction manager will apply a default
* timeout specific to the particular transaction manager.
*
*
A "+" before an exception name substring indicates that
* transactions should commit even if this exception is thrown;
* a "-" that they should roll back.
