Error with glossentry/@sortas

[frank-steimke]

Hi,

a glossentry with a @Sortas attribute leads to an error: "more than one item".
Caused by a bug in glossary.xsl line 27 which is
<xsl:sort select="(@sortas, normalize-space(db:glossterm[1]))" but should be
<xsl:sort select="(@sortas, normalize-space(db:glossterm))[1]"

DocBook xslTNG version 1.8.0 / 4af8cdd / SAXON PE 9.9.1.7

Greetings,
Frank Steimke
