NOTE: this issue is with the "serializatoin-with-dpath2" branch, not the current 0.15.0 branch.

Currently when using the function contains there is a SDE - "Schema Definition Error: Unsupported function: fn:contains

{xmlns:fn='http://www.w3.org/2005/xpath-functions'}

"

See tests:
test_contains_01
test_contains_02
