PATCH does not work on turtle

Hi all,
I was unsuccessfully trying to HTTP PATCH a turtle file. If I don't prefix the 'xsd' namespace the patch works.

Original resource:

@prefix : <#>.
@prefix as: <https://www.w3.org/ns/activitystreams#>.
@prefix xsd: <http://www.w3.org/2001/XMLSchema#>.
@prefix p: <./>.
@prefix notes: <../>.

p:546851bd-1db4-4b8d-bea2-1a33e982c73b
    a as:OrderedCollectionPage;
    as:partOf notes:mynotes;
    as:startIndex "0"^^<xsd:nonNegativeInteger>.

PATCH:

DELETE DATA { <https://diegoalbuquerque.localhost:8443/tests/collections/notes/pages/546851bd-1db4-4b8d-bea2-1a33e982c73b> <https://www.w3.org/ns/activitystreams#startIndex> "0"^^<http://www.w3.org/2001/XMLSchema#nonNegativeInteger>. }

RESULT:

The patch could not be applied. Could not find to delete: <https://diegoalbuquerque.localhost:8443/tests/collections/notes/pages/546851bd-1db4-4b8d-bea2-1a33e982c73b> <https://www.w3.org/ns/activitystreams#startIndex> "0"^^<http://www.w3.org/2001/XMLSchema#nonNegativeInteger> .

This works:

@prefix : <#>.
@prefix as: <https://www.w3.org/ns/activitystreams#>.
@prefix p: <./>.
@prefix notes: <../>.

p:546851bd-1db4-4b8d-bea2-1a33e982c73b
    a as:OrderedCollectionPage;
    as:partOf notes:mynotes;
    as:startIndex "0"^^<http://www.w3.org/2001/XMLSchema#nonNegativeInteger>.

Am I doing something wrong?

針對原始 Turtle 資源重現所提供的 PATCH，比較帶有前綴的 xsd:nonNegativeInteger 形式與完整的資料型別 IRI。追蹤 PATCH 處理以及 Turtle/RDF 剖析路徑；當資源使用 xsd prefix 時 DELETE DATA 請求能夠成功，並且有一個涵蓋兩種形式的回歸測試，即表示完成。
