This came up as a side issue to a question I asked a couple of weeks ago. A
fairly elegant solution relies on the fact that if an attribute is multiply
defined the last instance is used. It also exploits the fact that a copy-of
only copies if there is something to copy. Eg:
<input type="text">
<xsl:copy-of select="@text"/>
<xsl:copy-of select="@value"/>
<xsl:copy-of select="@size"/>
<xsl:copy-of select="@maxsize"/>
</input>
will give the type attribute a default of "text" and override it with any
supplied only if there is in fact a text attribute. The rest of the
attributes are only created if they were passed in.
