Tabularx table - break across page

Question

I have a table created using tabularx which is too big to fit onto one page. Is is possible to make it break across pages, whilst maintaining the current style?

I have tried to remove the table environment and keep the tabularxas suggested in this link TEX link but still have problems.

MWE:

Grateful for any advice and thanks in advance!

Here is a code with ltablex. Note the syntax, in particular for the caption, is the same as for longtable (\endhead, \endfoot and the like):
