XSL self-closing tags not expanding properly

[rzhao271]

As an example, for XSL files, cp should expand to <xsl:copy select="|" />, but right now it expands to <xsl:copy select="|">|</xsl:copy>.
This issue occurs for two reasons:

• In the snippets within expand-full.js, we have the mapping "cp": "xsl:copy[select]", without the / at the end. Therefore, the expander interprets the tag as one with content in between.
• Even if / is added to the end, the XSL content is interpreted as HTML and expands to <xsl:copy select="|">, which is not a valid self-closing tag within XSL.

Note to self: this issue should be fixed after migrating to the latest Emmet

It seems that in latest Insiders it still expands to <xsl:copy select=""></xsl:copy>

[rzhao271]

True. I'll currently leave that part as a wontfix, but I'll keep the issue open now that I realized:

• For cp/, Emmet doesn't automatically suggest <xsl:copy select="" /> 🩸
• When one expands cp/ via the 'Expand Abbreviation' command it becomes <xsl:copy select=""/> with no space before the /, though this could just be preferences more than anything.
