[basex-talk] xquery:eval() - handling of &

Hello,

The query

xquery:eval( 'contains(.,"&amp;")', map{'':<foo>&lt;&amp;&gt;</foo>} )

results in: [XPST0003] Invalid entity: '&")...'.

I can get the expected result if I double-escape the entity:

'contains(.,"&amp;amp;")'

or wrap in a call to serialize:

serialize('contains(.,"&amp;")')

However, both

xquery:eval( 'contains(.,"&lt;")', map{'':<foo>&lt;&amp;&gt;</foo>} )

and

xquery:eval( 'contains(.,"&gt;")', map{'':<foo>&lt;&amp;&gt;</foo>} )

return true, as expected.

Is this a bug, or am I missing something?

Thanks, Andrew
