Please provide XMLFormatProvider with RadSpreadProcessing so that we can import xml and export excel and vice a versa. This would be needed in UI fro win forms and asp .net as well.

The documents produced by WordsProcessing and SpreadProcessing are compliant with the specification. But, Open Office, Numbers and Pages (the default applications for working with .docx and .xlsx on MAC) are unable to open documents where the target attribute of the relationships of the documents is specified as an URI, instead of as a relative reference. According to the specification (Ecma Office Open XML Part 2 - Open Packaging Conventions) both formats are acceptable.

The issue is in the relationships parts, relationship element. The Target attribute can be either a URI (Target="/word/theme/theme1.xml") or a relative reference (Target="theme/theme1.xml") as stated in the specification. The document processing libraries use URI, which OpenOffice is unable to interpret, despite them being allowed by the specification.

The fix will be available in our official release Q2 2016.

The fix is available in our latest LIB release (v. 2015.1.0316)

From a custom function which inherit from FunctionBase it's possible to return some constant expressions like StringExpression or BoolExpression. But It's impossible to return a reference to a Cell or CellRange which will be used by another function by example or which will automatically update it's result.  There is no public constructor.

According to http://www.digitalpreservation.gov/formats/fdd/fdd000251.shtml#sign there should be two elements in the XMP-metadata to indicate the PDF/A conformance level.

Here is an example:
<rdf:Description rdf:about="" xmlns:pdfaid="http://www.aiim.org/pdfa/ns/id/">
  <pdfaid:part>1</pdfaid:part>
  <pdfaid:conformance>B</pdfaid:conformance>
</rdf:Description>

or attribute version:

<rdf:Description rdf:about="" xmlns:pdfaid="http://www.aiim.org/pdfa/ns/id/" pdfaid:part="1" pdfaid:conformance="B" />
