XML bans this type of mixed content because it has been causing
trouble in full SGML for over a decade.  The problem comes with
something like this:

<a>

<a></a>
</a>

After an SGML parser reads the opening <a> tag, it doesn't know
whether the element will contain #PCDATA or subelements.  The first
character it reads is a linefeed -- that's character data, so the
parser assumes that it is reading #PCDATA; when the parser finds the
<a> tag a few characters later it throws an error.

You need to do two things:

1) submit a bug report to Microsoft; and

2) create a new subelement to hold the text:

  <!ELEMENT a (text|a)>
  <!ELEMENT text (#PCDATA)>

  Now you can have

  <a>
  <text>This is some text</text>
  <a>

  or

  <a>
  <a>This is a subelement</a>
  </a>



All the best,


David
