+			Firstly, <m:name/> are a specification of a data format and as such are not bound to any programming language.
+			This specification is totally language- and plafform- independent.

+		<p>
+			The ideal/perfect language does not exist and our implementations will be written in various languages.
+			We started our prototype and first real implementations in C++ from several reasons:
+		</p>
+		<ul>
+			<li>It is mature and widespread: GCC runs almost everywhere and other compilers/toolchains are also available.</li>
+			<li>Programs written in C++ starts immediately: very important for CLI tools.</li>
+			<li>Can be seamlessly mixed with C and its libraries. Is good for interaction with the operating system.</li>
+			<li>Modern C++ is a quite good language.</li>
+			<li>We are not C++ gurus and C++ is not our first-choice language i.e. the fact that we are able to do implementation in C++ proves that the specification is simple enough to be reasonably implemented by an average software engineer in any other language :-)</li>
+		</ul>
+		
+		<p>Implementation in other languages will follow. Java is the next one. Then probably Perl, Python, Rust, Go, PHP etc. (depends on community involvement).</p>

 			Of course, you can use <m:name/> anywhere if it makes sense for you.
 			<m:name/> are designed to be generic enough – i.e. not specific to any industry (banking, telecommunications, embedded etc.) nor platform.
+			Data in this format are very concise, so can be used even in very small devices.
 			Its native data structure is a relation (table) but it can also handle tree-structured data (i.e. any data).
 			It is designed rather for streaming than for storage (but under some circumstances it is also meaningful to use it for storage).
