Saxon 9.7.0-10

The following query:

@@ declare namespace http = "http://www.expath.org/http"; declare namespace rest = "http://www.expath.org/restxq"; declare namespace p = "http://hl7.org/fhir"; declare variable $id external;

let $itr := collection("Patients")/p:Patient[p:id/@value = $id] return if ($itr) then for $ptn in $itr return (rest:response <http:response status="200"> {if ($ptn/p:Patient/p:meta/p:versionId/@value) then ( <http:header name="ETag" value="{$ptn/p:Patient/p:meta/p:versionId/@value}"/> <http:header name="Content-Location" value="/Patient/{$id}/_history/{$ptn/p:Patient/p:meta/p:versionId/@value}"/> ) else ( <http:header name="Content-Location" value="/Patient/{$id}"/> )} <http:header name="Last-Modified" value="{$ptn/p:Patient/p:meta/p:lastUpdated/@value}"/> </http:response>
</rest:response>, $ptn) else rest:response <http:response status="404" message="Patient with id={$id} was not found."/> </rest:response> @@

throws exception at compilation phase:

Syntax error on line 15 at column 30 of near {... <http:header name=} XPST0003: expected ")", found name "name"

if I comment out the line 15, or wrap the lines 14, 15 in a block like http:b...</http:b> then it does work properly. Should I rewrite the query in some other way, or this is a bug? May be there is a better way to achieve the same in XQuery?

Thanks, Denis.
