ApplyXSL enhancement request

[Michael Los <me...@mitre.org>]

In the file, ApplyXSL, for the servlet example, getContentType()
processes the media-type attribute of xsl:output to determine the
content type for the result.  I've pasted an enhancement to this method
below.  The enhanced method derives a default media-type value from the
method attribute if no media-type was found (as is the case with
default.xsl and default2.xsl provided with LotusXSL0_19_2).  Admittedly,
it doesn't follow all the fallback rules specified in Section 16 of the
XSLT spec since I don't have enough information to determine a default
if there is neither a method nor a media-type attribute.

If the content type is not specified, the browser may render the
returned HTML as text.  This is my experience while using Netscape
Navigator 4.7, Sun/Netscape iPlanet 4.0, JRun 2.3.3.
