Markup compatibility is discussed in (, 20Part%203%20-%20Markup%20Compatibility%20and%20Extensibility.zip), which is recommended reading to understand markup compatibility. Markup compatibility in the Open XML file formats specification In other words, interoperability is a function of support both in the file format and by applications. Notice that while the markup is supported in the document format, markup producers and consumers, such as Microsoft Word, must support it as well. This is supported through the use of a defined set of XML elements and attributes in the Markup Compatibility namespace of the Open XML specification. With respect to the Open XML file formats, markup compatibility is the ability for a document expressed in one of the above markup languages to facilitate interoperability between applications, or versions of an application, with different feature sets. Open XML defines formats for word-processing, spreadsheet and presentation documents in the form of specific markup languages, namely WordprocessingML, SpreadsheetML, and PresentationML. The Open XML SDK 2.5 supports markup compatibility in a way that makes it easy for you to achieve the above desired outcomes for and Office 2013 without having to necessarily become an expert in the specification details. The Office Open XML File Formats specification describes facilities for achieving the above desired outcomes in ECMA-376, Second Edition, Part 3 - Markup Compatibility and Extensibility. That is, you want the later version of Office to understand and support a feature employed in a document produced by Word 2013. Here too, you want the document to work as expected. When you open that document in Microsoft Word 2010, an earlier version, what should happen? Ideally, you want the document to remain interoperable with Word 2010, even though Word 2010 will not understand the new feature.Ĭonsider also what should happen if you open that document in a hypothetical later version of Office. Suppose you have a Microsoft Word 2013 document that employs a feature introduced in Microsoft Office 2013. Both are free.This topic introduces the markup compatibility features included in the Open XML SDK 2.5 for Office. I highly recommend SumatraPDF or MuPDF if you're after something a bit more.
You may or may not need an add-on or extension to do it, but it's pretty handy to have one open automatically when you click a PDF link online. Most web browsers, like both Chrome and Firefox, can open PDFs themselves. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use.
Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. Most people head right to Adobe Acrobat Reader when they need to open a PDF. PDF files always look identical on any device or operating system. The reason PDF is so widely popular is that it can preserve original document formatting.
The Portable Document Format (PDF) is a universal file format that comprises characteristics of both text documents and graphic images which makes it one of the most commonly used file types today. What is a PDF (Portable Document Format) file?
