PDF/A-1a is with conformance level A (for "accessibility"), and must adhere to all of the requirements of the PDF Reference as modified by the ISO 19005 specification. 

It requires structural and semantic properties to be preserved. Level 1a uses “Tagged PDF” and Unicode character maps to preserve the document's logical structure and content text stream in natural reading order. 

The following features are used:
- Language specification
- Hierarchical document structure
- Tagged text spans and descriptive text for images and symbols
- Character mappings to Unicode

The purpose is to improve accessibility and make the content accessible for screen readers.

Some fonts don't include bold and italic font styles. These fonts can be exported with the default typeface, and additional transformation could be applied to the letters itself - e.g. skew transform for the italic.

Note: Make sure that this will also work when exporting to PDF in WordsProcessing.

The standard fonts listed at http://docs.telerik.com/devtools/wpf/controls/radpdfprocessing/concepts/fonts#standard-fonts cannot be embedded in a document. Using one of them prevents the document from complying with PDF/A standard.

Currently, PdfStreamWriter writes only PDF pages.

If we implement API for merging multiple pages or whole documents we would be able to preserve links between pages (which are currently being corrupted).

Merging whole documents would also allow preserving document properties (bookmarks, interactive forms, ...). For a more detailed list of the unsupported document properties you can refer to our documentation: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfstreamwriter/features.

We may also implement API for adding initial document properties from some existing PDF file.

Currently, Standard fonts are exported always with StandardEncoding. This does not allow export of some special characters which do not fit in the first 255 glyph definitions in the font. Most of these characters are the ones with an accent such as "Eacute" glyph (É) which is with position number 303 in Times Roman font. The list of all standard fonts may be found in this documentation section:

The hierarchical document structure is a means to describe the PDF document structure, which is currently not supported. See 10.6.1 Structure Hierarchy on 856 page of the PDF specification for details.
This document structure is an alternative to the standard PDF structure and most non-Adobe software does not support it.

The document might have been created with Adobe software like Adobe LiveCycle Designer. Very often the document contains some fallback text in the standard PDF structure like:
"Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document."
"The document you are trying to load requires Adobe Reader 8 or higher. You may not have the Adobe Reader installed or your viewing environment may not be properly configured to use Adobe Reader. For information on how to install Adobe Reader and configure your viewing environment please see  http://www.adobe.com/go/pdf_forms_configure."
"For the best experience, open this PDF portfolio in Acrobat X, Reader X, or later."

In principle, the blend function B (Cb , Cs ) is used in the compositing formula to customize the blending operation in Adobe transparency imaging model. The blending mode may define any function which yields another result color from the backdrop and source colors. This will allow overlaying objects on each other forming a transparency stack.

Support for the Blend Mode parameter of the external graphic state should be implemented.
