Correct it can't be done in XSLT 1.0.

Saxon has an extension saxon:call-template that does this.

But there is a workaround that doesn't need extensions: it's a technique
introduced by Dimitre Novatchev in his FXSL library. Essentially, if you
have a template

<xsl:template name="x">

then add a match pattern:

<xsl:template name="x" match="dynamic:x"/>

Define a variable whose value is a node:

<xsl:variable name="dynamic:x"><dynamic:x/></xsl:variable>

Now you can define a variable:

<xsl:variable name="templateToCall" select="$dynamic:x/*"/>

and do:

<xsl:apply-templates select="$templateToCall"/>

which in this case will call the template dynamic:x, but can be adapted to
call whatever template the variable templateToCall is set to.
