I created a test that contains a sequence of delimited-length integer elements. Each element has an initiator but there are no terminators or separators defined. The parser is unable to detect the second element's initator in order to finish parsing the first element. Is this the expected behavior?

The test is test_entityAndNonMix_02:

[error] Test edu.illinois.ncsa.daffodil.section06.entities.TestEntities_01.test_entityAndNonMix_02 failed: java.lang.Exception: Parse Error: Convert to Integer (for xs:int): Unable to parse '1 SP2' (using up all characters).

The 1 should be parsed as the first element, and the 2 should be the second. The test is in the following files:
