iTextSharp 5.5.10
iTextSharp 5.5.9
更新細節：
* Improvements:
# Tagged PDF and accessibility
- Fixed an issue with tagging of nested lists.
- Improvements in tagging of form XObjects.
- When adding multiple Chunks to a Phrase, there's an optimization of merging them when they have the same properties. But this resulted in their accessibility attributes and roles being overwritten.
# PDF/A
- Corrected the allowed annotation types for PDF/A-1, PDF/A-2 and PDF/A-3.
- Fixed issues with output intents in PDF/A. We incorrectly flagged the generated PDF/A document as invalid when stamping an existing PDF/A document. There was also an issue when merging PDF/A documents.
# Text extraction
- Refactored our text extraction implementation to make it more customizable.
