Splitting up IN... entries

Hi,

I've got an idea: Is there any reason to define the article and the
journal together, e.g.:

  <article id="sampling" xml:lang="en">
    <author>
      <name nametype="familylast">
        <given>Jan</given>
        <family>Rijkhoff</family>
      </name>
      <name nametype="familylast">
        <given>Dik</given>
        <family>Bakker</family>
      </name>
    </author>
    <title>Language Sampling</title>
    <journal>Linguistic Typology</journal>
    <volume>2</volume>
    <number>3</number>
    <pages>263--314</pages>
    <year>1998</year>
  </article>

instead of:

  <article id="sampling" xml:lang="en">
    <crossref id='sampling-PART2'/>
    <author>
      <name nametype="familylast">
        <given>Jan</given>
        <family>Rijkhoff</family>
      </name>
      <name nametype="familylast">
        <given>Dik</given>
        <family>Bakker</family>
      </name>
    </author>
    <title>Language Sampling</title>
    <pages>263--314</pages>
  </article>

  <magazine id="sampling-PART2" xml:lang="en">
    <journal>Linguistic Typology</journal>
    <volume>2</volume>
    <number>3</number>
    <year>1998</year>
  </magazine>

The same applies to InBook -> Book, InCollection -> Book and
InProceedings -> Proceedings.

Currently, both are possible, but it makes the DTD rather complicated.
Furthermore, BibTeX will move a crossref'ed entry into the
crossref'ing entry if it is crossref'ed only once (actually defined by
the -min-crossrefs command line option to BibTeX), but AFAIK this
breaks if some entries are defined with crossrefs while other entries
are not.

So my question is:  Is there any need for allowing both (apart from
convenience when inputting the entry)?

Cheers,

Thomas
