 == Introduction ==
 This is an introductory text to XML, the extensible markup language used for our texts. 
+
+There is also the [http://www.w3.org/TR/xml/ W3C Recommendation].
+
+== Basic facts about XML ==
+ * An XML document is a plain text file, preferably in Unicode encoding
+ * The structure is made up out of nested elements, like a matroshka.
+  {{{
+   <root>
+      <nestedElement>With content</nestedElement>
+      <anotherElement with="attribute" another='one'>Elements can have attributes </emptyTag>, as well</anotherElement>
+      <!-- I am a comment <hidden>everything here is</hidden> ignored -->
+      <question>did we already talk about &amp; entities?</question>
+   </root>
+   }}}
+   As with a matroshka, also in XML, you cannot put half a puppet into the bigger puppet: they have to be properly nested.
+ ** Some characters are forbidden, they have to be escaped:
+    - {{{<}}}: {{{&lt;}}}
+    - {{{>}}}: {{{&gt;}}}
+    - {{{&}}}: {{{&amp;}}}
+    To a lesser extent, namely only in attribute values
+    - {{{"}}}: {{{&quot;}}}
+    - {{{'}}}: {{{&apos;}}}
