| What is the rational for ignoring the XHTML namespace by default?

I think the idea was that XHTML is likely to be one of the most common
documentation vocabularies and it's not every going to be a reasonable
extension vocabulary, so why make authors add p:ignored-prefixes="h" on
all their pipelines.

However, it has also been suggested that documentation be allowed anywhere,
even in p:inline and we have no mechanism for "un-ignoring" a prefix.
Those two ideas aren't compatible if I want a pipeline that takes XHTML
on a p:inline, so...I'm more and more in favor of not having this default.

The p:inline example, btw, is this:


  <p:identity p:ignore-prefixes="db" xmlns:db="http://docbook.org/ns/docbook">
    <p:input port="source">
      <p:inline>
<db:para>This port provides some XHTML that is always provided as the
output of this identity step.</db:para>
<div xmlns="http://www.w3.org/1999/XHTML">
<p>Some content</p>
</div>
     </p:inline>
   </p:input>
  </p:identity>

I'm not entirely sure I like having documentation inside p:inline, but
it is certainly possible to write a consistent story about it.
