word document where document_summary_info_id D5CDD505-2E9C-101B-9397-08002B2CF9AE

[Beskow, Christer]

I'm using POIFS to read and write CustomProperties to the 
DocumentSummaryInformation.
Some word documents only contain a section with formatId 
D5CDD505-2E9C-101B-9397-08002B2CF9AE, which is the second id in 
SectionIDMap.DOCUMENT_SUMMARY_INFORMATION_ID. 
When I try to create an instance of DocumentSummaryInformation , method 
isDocumentSummaryInformation in PropertySet returns false, as it only compares 
the formatId of the section with the first id. This results in a 
org.apache.poi.hpsf.UnexpectedPropertySetTypeException: Not a 
org.apache.poi.hpsf.DocumentSummaryInformation.


Is it safe to alter the code so that isDocumentSummaryInformation() also 
returns true if the id is D5CDD505-2E9C-101B-9397-08002B2CF9AE instead of 
D5CDD502-2E9C-101B-9397-08002B2CF9AE?

I'm using 3.1-Final.

thanks in advance,
Christer
