A link in the metadata for generated HTML files calls for a stylesheet that is part of the DITA toolkit. There are two problems:
1. The stylesheet doesn't actually appear in the output directories for the documentation, so it is not used.
2. The link currently appears with the absolute pathname of the stylesheet in the temp directory for each document. For the Latest Alpha Manuals currently, for example, it looks like this for a page in the Getting Started guide:
<link href="C:\nightlies\docs-trunk\out\getstarttemp\commonltr.css" type="text/css" rel="stylesheet" />
Specifying an absolute pathname is obviously not desirable, because the pathname reflects where the docs were built, not where they are installed, and because the temp directory disappears after the docs are built anyway.
There's a simple fix for each of these problems.
