[Exist-open] json serialize problem

[Grant MacKenzie]

Check your dataset instance with 'instance of'
I think you will find you want a 'instance of element()'
not 'instance of document-node()' for your result dataset
try to get the root element with '/*'
eg. /db/ehr/v2')//DataSet[HDSN00.01.013/@value="a894317f-53da-486f-a1df-cea23200273d"]/*

this maybe better:
<root>{ collection('/db/ehr/v2')//DataSet[HDSN00.01.013/@value="a894317f-53da-486f-a1df-cea23200273d"]}</root>
