I don't know if this is just a typo in the example, but the
namespace-URI begins with a space-character:
<svg xmlns:xml=" http://www.w3.org/1998/XML">

$ xmllint --debug xmlns.xml
xmlns.xml:2: namespace error : xml namespace prefix mapped to wrong URI
<svg xmlns:xml=" http://www.w3.org/1998/XML">
                                            ^
DOCUMENT
version=1.0
URL=xmlns.xml
standalone=true
namespace xml href=http://www.w3.org/XML/1998/namespace
  ELEMENT svg
    TEXT interned
      content=
    ELEMENT a
      ATTRIBUTE id
        TEXT
          content=first
      ATTRIBUTE space
        TEXT
          content=default
    TEXT interned
      content=

Just an info: Libxml2 strips all explicit declarations of the XML
namespace, since it stores the XML ns-declaration in a special field on
the doc itself, namely in xmlDoc->oldNs. The XML namespace declaration
is "built-in" by every XML processor, so you don't have to declare it.
