Custom XML Attribute Name for XSLT

I have a XSLT that generate AngularJS, with model=’xxx’

Now, I have to make a XSLT to use the same source but the target will be Angular6,

I Change my XSLT to this: (only model to [(model)])

<xsl:template name="InputText">
    <div class="input-group">
    <input type="{@type}" class="form-control {@class}"
    <xsl:attribute name="[(model)]">
         <xsl:value-of select="@model"/>

But, when I transform I have the following message:

FATAL ERROR:  'line 131: You cannot call an attribute '[(model)]''

I understand the error, but my question is, I must to use some escape or additional parameter.

Test: My xslt execution is with Java.

Source: AngularJS
