A quick question since I'm on my way out the door and I can't check right now:
Does XOM support XPointer with XInclude?

XOM supports XPointers. However it does not support the xpointer scheme, which never made it out of candidate status and has been abandoned by the W3C. It does support the element scheme and bare name XPointers.

In other words, something like this will work, if I have precisely 10 items in head.xml:

<head>
<xi:include href="head.xml" xpointer="element(common/1)"/>
<xi:include href="head.xml" xpointer="element(common/2)"/>
<xi:include href="head.xml" xpointer="element(common/3)"/>
<xi:include href="head.xml" xpointer="element(common/4)"/>
<xi:include href="head.xml" xpointer="element(common/5)"/>
<xi:include href="head.xml" xpointer="element(common/6)"/>
<xi:include href="head.xml" xpointer="element(common/7)"/>
<xi:include href="head.xml" xpointer="element(common/8)"/>
<xi:include href="head.xml" xpointer="element(common/9)"/>
<xi:include href="head.xml" xpointer="element(common/10)"/>

head.xml

<head xmlns="http://www.w3.org/1999/xhtml"; xml:id="common" xml:lang="en">

... 10 <link>, <meta> and <script> items to import

</head>

It's hard to know whether this is even worthwhile. I suppose it means I can keep all of the common stuff in head.xml and edit it once for all of the pages that share it, but if I ever add or remove a line from head.xml I have to go find all of the files that include it and change the number of xi:includes to match.

Is it just me or was the element() scheme completely crippled to avoid letting it compete with the full xpointer() scheme?
Was it just kept so simplistic so as to make sure no one could find an objection to it?

There's really no way to specify any kind of wildcard or range is there?
Wow. This seriously limits what you can do with XInclude doesn't it? Is there anything on the horizon that has anything like the power of the xpointer() scheme? Are you fundamentally opposed to implementing some sort of xpath support for use with XInclude?
