• fixed validation of digital signature ByteRange array;
• fixed recursive links of color spaces;
• fixed validation of spaces in the indirect object header;
• fixed Crypt filter handling;
• fixed misprint in ‘Lbl’ structure tag; and
• added support for glyphs with CIDs > 65535 (with an appropriate validation. error)

Policy checker:

• fixed feature extraction from encrypted documents.

Test corpus:

• added new test corpus for the Technical Working Group resolutions;
• fixed test file for digital signature validation; and
• fixed test files for Extension Schema definitions in XMP.
