[jira] [Commented] (PDFBOX-2378) XMPBox removes namespaces on serialization

    [ https://issues.apache.org/jira/browse/PDFBOX-2378?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15628331#comment-15628331 ] 

Kacper Zielinski commented on PDFBOX-2378:
------------------------------------------

I have the same problem in 2.0.3 - namespaces defined in ref:Description are lost after parse/serialization. 

<rdf:Description xmlns:pdfaExtension="http://www.aiim.org/pdfa/ns/extension/" xmlns:pdfaSchema="http://www.aiim.org/pdfa/ns/schema#" xmlns:pdfaProperty="http://www.aiim.org/pdfa/ns/property#" rdf:about="">
....

results as:

<rdf:Description rdf:about="" xmlns:pdfaExtension="http://www.aiim.org/pdfa/ns/extension/">
....
 
The prefixes are also not present in other elements.
