Changelog:

iText Core - PDF/A - Xtra - XML Worker 5.5.10

Fix issue with multiple consequent tabs in case of right-to-left line
DEV-1701
Make XMLWorker CssApplier framework extensible
Make XMLWorker CssApplier setters public
Disable strict javadoc checking for javadoc:aggregate
Root POM wasn't bumped to 5.5.10-SNAPSHOT
That's more cosmetic, because the POM is only used as an aggregater, not as a parent for the modules.
Improved aggregated report
Run with: mvn javadoc:aggregate
AGPLv3 in MarkDown format
Source: https://github.com/IQAndreas/markdown-licenses
The text is identical to http://www.gnu.org/licenses/agpl-3.0.txt, only the formatting was changed to look better on GitHub/GitLab sites.
Make XMLWorker CssAppliers framework generic
Only allow subclasses of iText Elements in Map<>
Improve XMLWorker CssApplier docs & license header
XmlWorker: set default context key to class name of parent class for all descendants of CSSResolverPipeline and HtmlPipeline
This fixes a problem of unavailability of corresponding pipelines in descendant classes are registered since the context keys are hardcoded. Now descendant classes will be correctly fetched if pipelines are overriden and for deep XmlWorker customization one would have to override getContextKey() and corresponding getHtmlPipelineContext() and getCSSResolver() for AbstractTagProcessor implementation
DEV-1703
Bump version of maven javadoc plugin
Enable taggedPdfADocumentUsingExternalCacheTest
Closes DEV-1561
Added documentation for markUsed
Allow getting next MCID without using it (XTRA)
DEV-1706 (request from SUP ticket)
Minor code fix in clean up tool
Fix paths in a test
Fix text alignment for <p> and <div> tags in case of right-to-left text
Fix default run direction support for bidi algorithm, change default value of the run direction variables for layout elements
Fix test failure. Avoid unnecessary static global variables changes in tests
Make default text chunk location class public
Fixed bug with XML parser not processing XML entities in attributes.
Now special XML entities are processed correctly (e.g. & to &) when they're in an attribute value. Also, made related changes to tests, where we store html request with symbol "&" in annotations. DEV-1735
Remove $Id$ macros
Jgit does not support .gitattributes and does not use the ident macro. This causes `jgit blame` not to work correctly (SonarQube needs this). Closes QA-76
Port itextsharp github pull request #18: Add 'SuppressTagging' property to PdfContentByte.
DEV-1744
Disallow Q operator in a BT-ET block
Restore matrix when disallowing Q in BT-ET

Change error message for conflict in RoleMap entry
DEV-1740
Fix leading of paragraphs in XmlWorker in case of not default font sizes
DEV-1749
Replace Indicator parameter type from Boolean to boolean for SpecifiedTradeAllowanceCharge
SpecifiedTradeAllowanceCharge has a 1 .. 1 cardinality for Indicator in the ZUGFeRD 1.0 Technical Documentation, so null values shall not be passed to addSpecifiedTradeAllowanceCharge. Moreover, passing null value would lead to exception as Boolean is unboxed further in code anyway
Arabic: fix isolated fonts in \uFxxx ranges
If an isolated form is not available in the \uFxxx range, fall back to the base glyph in the \u06xx range. e.g. if \uFE8D (isolated alif) doesn't exist in a font, fall back to \u0627. Fixes SUP-1495
port pull request #21 from .NET to Java
DEV-1774
Set Java version of xtra to Java 7
Closes DEV-1766
OCGParser: Fix exceptions of parsing inline images
DEV-1786
SUP-1486 Add check in PdfReader to see if the authentication event is EFOPEN. Previously we had no check for it and encountered a BadpasswordException when trying to open the Pdf even though only the attachments are encrypted. Encryption check will now be skipped if the authentication event is EFOPEN and there is no password provided.
SUP-1513 Made the readPages method more lenient towards typos
Add additional documentation to PdfReader
The method GetNumberOfPages() behaves differently depending on whether the reader was opened in partial mode. The method documentation has been updated to reflect this. SUPP-1552
updating encryption documentation
updating encryption documentation on PdfStamper
Add soft hyphens to word boundaries for word hyphenation detection. Avoid writing soft hyphens to the output
DEV-1795
Fix additional documentation to PdfReader
Cleaner and correct version of the additional documentation SUP-1552
BarcodeDataMatrix: add possibility to force the square size of barcode
DEV-1801
Change behavior of pdfReader#computeUserPassword in case of AES256 encryption. Add corresponding test.
As stated in Acrobat Supplement to the ISO 32000 in revision 5 (AES256) of standard security handler the user and owner keys where made independent. So the computing of user password from owner password isn't supported. The behavior was changed to return null in that case and now it matches the one in iText7. DEV-1802
Fix thread safety issues in OCGParser
DEV-1797
Fix Image binary transparency bug
Transparent pixels in ARGB images sometimes were mistreated as non transparent. See http://stackoverflow.com/questions/39119776/itext-binary-transparency-bug
This commit also contains additional fix suggested by Michael Klink DEV-1796
Add support for signature policy for EPES signatures support
This is originally suggested by J. Arturo DEV-1806
Fix Xmlworker eating chars when parsing &
When Xmlworker encountered a '&' followed by a ' ', it would leave the special char state without appending the ' '. Update broken cmp-files SUP-1596
Handle NPE when removing floating AcroField
Fix Acrofields present in the document but not linked to the annotations dic throwing and NPE when they are removed SUP-1602
