This is probably a duplicate, but I haven't found the answer from any other posts so I will go ahead and ask.

Inside an XSL file, I'd like to have variables that are the namespaces that will be output.

Something like:

```
<xsl:variable name="some_ns" select="'http://something.com/misc/blah/1.0'" />

```

Then in a template, do this:

```
<SomeElement xmlns="$some_ns">

```

I have had no luck getting this work, even though it seems rather simple.

Thanks for your time.
