At this point, the justify alignment is not supported. Provide the ability to export text with this setting.
This functionality is dependent on PdfProcessing: Provide API for setting the text alignment to Justify

Implement page border property which could be applied over the whole document or over a specific page.

Generate a document with the following approach: https://docs.telerik.com/devtools/document-processing/knowledge-base/populate-table-data-mail-merge

Before calling MailMerge, add two document variables with the editor: https://docs.telerik.com/devtools/document-processing/libraries/radwordsprocessing/concepts/fields/document-variables 

 Replace cannot match whole word with special characters (e.g. "#", "@", "&") at the start/end.

Workaround (RegEx):

editor.ReplaceText(new Regex($"(?<=\\s|^|[\\c_]){placeholder}(?=\\s|$|[\\c_])"),"new content");

Add support for Picture Styles.

The mail merge should support conditional fields. Here is an example:

{ IF [Condition] [Display Result 1] [Display Result 2] }

InvalidOperationException when cloning a document containing fields spanning multiple paragraphs.

Workaround: instead of new paragraphs, use line breaks (Shift+Enter).

The default vertical alignment value of table data (<td>) is incorrect.

Current: "vertical-align: top;"

Expected: "vertical-align: middle;"

Workaround: Explicitly set the "vertical-align: middle;" of <td> elements.
