Top-level elements
The Top Level entity defines the elements that can occur within the Stylesheet (or Transform) element. It forces all Import elements to appear first (if any occur at all), and then allows any mixture of other allowed elements:
<!ENTITY % top-level "
(xsl:import*,
(xsl:include | xsl:strip-space |
xsl:preserve-space | xsl:output |
xsl:key | xsl:decimal-format |
xsl:attribute-set | xsl:variable |
xsl:param | xsl:template |
xsl:namespace-alias
%non-xsl-top-level;)*) ">
Note that the Template and Variable elements shown in this list are described in the next section. The other elements are described below.
A mechanism for adding non-XSLT elements to this group is provided by the entity reference at the end. But the Non-XSL Top Level entity is initially empty:
<!ENTITY % non-xsl-top-level " " >
The Top Level entity is referenced from two places, namely from the Stylesheet element definition and from the Transform element definition:
<!ELEMENT xsl:stylesheet %top-level;> <!ELEMENT xsl:transform %top-level;>
For example:
<xsl:stylesheet ...> <xsl:import .../> <xsl:import .../> <xsl:template ...>...</xsl:template> <xsl:template ...>...</xsl:template> </xsl:stylesheet>
There are also a number of attributes that these two elements can take, and these are grouped within the Top Level Attributes entity:
<!ENTITY % top-level-atts " extension-element-prefixes CDATA #IMPLIED exclude-result-prefixes CDATA #IMPLIED id ID #IMPLIED version NMTOKEN #REQUIRED xmlns:xsl CDATA #FIXED "http://www.w3.org/1999/XSL/Transform" %space-att; <!ATTLIST xsl:stylesheet %top-level-atts;> <!ATTLIST xsl:transform %top-level-atts;>
Import element
The Import element is defined as follows:
