Re: [Serial] XHTML Serialization (qt-2004Nov0025-08)

Hi Bjoern

In [1], you submitted the following comment on the October 29 Working 
Draft of XSLT 2.0 and XQuery 1.0 Serialization:

---------------------------------
Please add a note that this process removes possible parameters in the 
attribute value, i.e. that

  <meta http-equiv="Content-Type" content="text/html;version='3.0'" />

in the data model instance would be replaced by e.g.

  <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
---------------------------------

Thank you for submitting this comment.  The editor added this note.
