Deploying a freshly made transform will fail

[peetkes]

I just created a transform
ml transform tst:test
This creates a test.xslt in rest-api/transform
When I deploy this I get this Error:
ERROR: 400 "Bad Request"
ERROR: <rapi:error xmlns:rapi="http://marklogic.com/rest-api">rapi:status-code400/rapi:status-coderapi:statusBad Request/rapi:statusrapi:message-codeRESTAPI-INVALIDCONTENT/rapi:message-coderapi:messageRESTAPI-INVALIDCONTENT: (err:FOER0000) Invalid content: invalid sample extension: could not parse XSLT extension sample; please see the server error log for detail XDMP-BADCHAR: (err:XPST0003) Unexpected character found '&' (0x0026)/rapi:message/rapi:error

This is caused by the fact that { } is not escaped when the transform is deployed.
