Bug #4246

XSLT variable contains document node with zero-length text node
100%
Description
The construct
<xsl:variable name="x">
<xsl:sequence select="()"/>
</xsl:variable>
produces a document node containing a single zero-length text node child. Zero-length text nodes should never occur under the rules for constructing complex content.
Saxon is using the "TextFragment" data structure for this, and in this data structure there is always a text node even if it is empty.
This is probably one of those bugs that has been in the product "for ever".

Patch committed for 9.9 and trunk. The patch to DocumentInstr creates a conventional (LinkedTree) document node rather than a TextFragmentValue in the case where the text is zero-length.

These new tests are failing when bytecode generation is enabled.

I've moved the logic that decides whether to create a TextFragmentValue into a static factory method, which is now invoked both by the interpreted and the compiled code. Tests now passing.
